GENERAL DESCRIPTION
The ADA4665 is a family of rail-to-rail input/output single
supply and dual supply amplifiers optimized for lower power
budget designs where the signal chain requires some gain
stages requiring amplifiers higher gain bandwidth and faster
response.
4
The ADA4665 family features an extended operating range
with supply voltages from 5V up to 16 V for low power
operation with ISY of 500 μA typically and 900 μΑ over the
extended industrial temperature. These devices offer 3MHz
unity gain bandwidth. They also feature low input bias currents
of 1pA and 10 mA output drive.
The combination of low supply currents, low offsets, very low
input bias currents, and wide supply range make these
amplifiers useful in a wide variety of low power applications.
