GENERAL DESCRIPTION
The OP200 is the first monolithic dual operational amplifier
to offer OP77 type precision performance. Available in the
industry standard 8-lead pinout, the OP200 combines precision
performance with the space and cost savings offered by a dual
amplifier.
Power consumption of the OP200 is low, with each amplifier
drawing less than 725 μA of supply current. The total current
drawn by the dual OP200 is less than one-half that of a single
OP07, yet the OP200 offers significant improvements over this
industry-standard op amp. The voltage noise density of the
OP200, 11 nV/√Hz at 1 kHz, is half that of most competitive
devices.
www.BDTIC.com/ADI
The OP200 features an extremely low input offset voltage of
less than 75 μV with a drift below 0.5 μV/°C, guaranteed over
the full military temperature range. Open-loop gain of the OP200
exceeds 5,000,000 into a 10 kΩ load; input bias current is under
2 nA; CMRR is over 120 dB; and PSRR is below 1.8 μV/V. On-chip
Zener zap trimming is used to achieve the extremely low input
offset voltage of the OP200 and eliminates the need for offset
pulling.
The OP200 is pin compatible with the OP221, LM158,
MC1458/MC1558, and LT1013.
The OP200 is an ideal choice for applications requiring multiple
precision op amps and where low power consumption is critical.
For a quad precision op amp, see the OP400.

OP200
APPLICATIONS INFORMATION
The OP200 is inherently stable at all gains and is capable of
driving large capacitive loads without oscillating. Nonetheless,
good supply decoupling is highly recommended. Proper supply
decoupling reduces problems caused by supply line noise and
improves the capacitive load driving capability of the OP200.
DUAL LOW POWER INSTRUMENTATION
AMPLIFIER
A dual instrumentation amplifier that consumes less than 33 mW
of power per channel is shown in Figure 30. The linearity of the
instrumentation amplifier exceeds 16 bits in gains of 5 to 200 and is
better than 14 bits in gains from 200 to 1000. CMRR is above
115 dB (gain = 1000). Offset voltage drift is typically 0.2 μV/°C
over the military temperature range, which is comparable to the
best monolithic instrumentation amplifiers. The bandwidth of
the low power instrumentation amplifier is a function of gain
and is shown in Table 7.
PRECISION ABSOLUTE VALUE AMPLIFIER
The circuit in Figure 31 is a precision absolute value amplifier
with an input impedance of 10 MΩ. The high gain and low TCVOS
of the OP200 ensure accurate operation with microvolt input
signals. In this circuit, the input always appears as a commonmode signal to the op amps. The CMRR of the OP200 exceeds
120 dB, yielding an error of less than 2 ppm.

DUAL 12-BIT VOLTAGE OUTPUT DAC
DUAL PRECISION VOLTAGE REFERENCE
The dual output DAC shown in Figure 33 is capable of providing
untrimmed 12-bit accurate operation over the entire military
temperature range. Offset voltage, bias current, and gain errors
of the OP200 contribute less than 1/10 of an LSB error at 12 bits
over the military temperature range.
A dual OP200 and a REF43, a 2.5 V reference, can be used to
build a ±2.5 V precision voltage reference. Maximum output
current from each reference is ±10 mA with load regulation
under 25 μV/mA. Line regulation is better than 15 μV/V and
output voltage drift is under 20 μV/°C. Output voltage noise
from 0.1 Hz to 10 Hz is typically 75 μV p-p. R1 and D1 ensure
correct startup.
