These amplifiers use a patented trimming technique that achieves superior precision without laser trimming. The parts are fully specified to operate from 1.8 V to 5.0 V single supply or from ±0.9 V to ±2.5 V dual supply. The combination of low offsets, lowhttp://www.mianfeiwendang.com/doc/ea0f083302a80ec7e2c19ac3 noise, very low input bias currents, and low power consumption make the AD8603/AD8607/AD8609 especially useful in portable and loop-powered instrumentation. The ability to swing rail to rail at both the input and output enables designers to buffer CMOS ADCs, DACs, ASICs, and other wide output swing devices in low power single-supply systems. The AD8603 is available in a tiny 5-lead TSOT-23 package. The AD8607 is available in 8-lead MSOP and SOIC packages. The AD8609 is available in 14-lead TSSOP and SOIC packages. Rev.

A | Page 11 of 16 AD8603/AD8607/AD8609 APPLICATIONS NO PHASE REVERSAL The AD8603/AD8607/AD8609 do not exhibit phase inversion even when the input voltage exceeds the maximum input common-mode voltage. Phase reversal can cause permanent damage to the amplifier, resulting in system lockups. The AD8603/AD8607/AD8609 can handle voltages of up to 1 V over the supply. The use of the snubber circuit is usually recommended for unity gain configurations. Higher gahttp://www.mianfeiwendang.com/doc/ea0f083302a80ec7e2c19ac3in configurations help improve the stability of the circuit. Figure 44 shows the same output response with the snubber in place. 文档下载 免费文档下载 http://www.mianfeiwendang.com/ VOLTAGE (1V/DIV) Figure 42. Output Response to a 2 nF Capacitive Load, without Snubber If a voltage 1 V higher than the supplies is applied at either input, the use of a limiting series resistor is recommended. If both inputs are used, each one should be protected with a series resistor. To ensure good protection, the current should be limited to a maximum of 5 mA. The value of the limiting resistor can be determined from the equation (VIN – VS)/(RS 200 Ω) ≤ 5 mA L 04356-A-039 Figure 43. Snubber Network DRIVING CAPACITIVE LOADS The AD8603/AD8607/AD8609 are capable of driving large capacitive loads without 文档下载 免费文档下载 http://www.mianfeiwendang.com/ oscillating. Figure 42 shows the output of the AD8603/AD8607/AD8http://www.mianfeiwendang.com/doc/ea0f083302a80ec7e2c19ac3609 in response to a 100 mV input signal, with a 2 nF capacitive load. Although it is configured in positive unity gain (the worst case), the AD8603 shows less than 20% overshoot. Simple additional circuitry can eliminate ringing and overshoot. One technique is the snubber network, which consists of a series RC and a resistive load (see Figure 43). With the snubber in place, the AD8603/AD8607/AD8609 are capable of driving capacitive loads of 2 nF with no ringing and less than 3% overshoot. Figure 44.

One of the most common applications is liquid level sensing in tanks. This is particularly popular in pharmaceutical environments where a tank must know when to stop filling or mixing a given liquid. In aerospace applications, these sensors detect the level of oxygen used to propel engines. Whether in a combustible environment or not, capacitive sensors generally use low voltage. The precision and low voltage of the AD8603/AD8607/AD8609 make the parts an excellent choice for such applications. COMPOSITE AMPLIFIERS A composite amplifier can provide a very high gain in applications where high closed-loop dc gains are needed. The high gain achieved by the composite amplifier comes at the expense of a loss in phase margin. Placing a small capacitor, CF, in the feedback in parallel with R2 (Figure 45) improves the phase margin. Picking Chttp://www.mianfeiwendang.com/doc/ea0f083302a80ec7e2c19ac3F = 50 pF yields a phase margin of about 45° for the values shown in Figure 45. A composite amplifier can be used to optimize dc and ac characteristics. Figure 46 shows an example using the AD8603 and the AD8541. This 文档下载 免费文档下载 http://www.mianfeiwendang.com/ circuit offers many advantages. The bandwidth is increased substantially, and the input offset voltage and noise of the AD8541 become insignificant since they are divided by the high gain of the AD8603. The circuit of Figure 46 offers a high bandwidth (nearly double that of the AD8603), a high output current, and a very low power consumption of less than 100 ?A. Rev.

The parts are tested at 5 V, 3.3 V, 2.7 V, and 1.8 V and are suitable for various applications whether in single or dual supply. In addition to their low offset voltage and low input bias, the AD8603/AD8607/AD8609 have a very low supply current of network at the output to reduce the noise. The signal bandwidth can be calculated by ? π R2C2 and the closed-loop bandwidth is the intersection point of the open-loop gain and the noise gain. The circuit shown in Figure 47 has a closed-loop bandwidth of 58 kHz and a signal bandwidth of 16 Hz. Increasing C2 to 50 pF yields a closed-loop bandwidth of 65 kHz, but only 3.2 Hz of signal bandwidth can be achieved. 40 ?A, making the parts an excellent choice for portable electronics. The TSOT package allows the AD8603 to be used on smaller board spaces. PHOTODIODES Photodiodes have a wide ohttp://www.mianfeiwendang.com/doc/ea0f083302a80ec7e2c19ac3f range applications from bar code scanners to precision light meters and CAT scanners. The very low noise and low input bias current of the AD8603/AD8607/ AD8609 make the parts very attractive amplifiers for I-V conversion applications. Figure 47 shows a simple photodiode circuit. The feedback capacitor helps the circuit maintain stability. The signal 文档下载 免费文档下载 http://www.mianfeiwendang.com/ bandwidth can be increased at the expense of an increase in the total noise; a low-pass filter can be implemented by a simple RC Rev.
