General Description

Software Programmable Gain Amplifier AD526 PIN CONFIGURATION DIG GND 1 NULL 2 VIN 3 NULL 4 16 15 14 A1 A0 CS CLK TOP VIEW ANALOG GND 2 5 (Not to Scale) 12 A2 AD526 13 ANALOG GND 1 6 –VS 7 VOUT SENSE 8 11 10 9 B +VS VOUT FORCE The AD526 is a single-ended, monolithic software programmable gain amplifier (SPGA) that provides gains of 1, 2, 4, 8 and 16.

It is plete, including amplifier, resistor network and TTL-patible latched inputs, and requires no external ponents.

Low gain error and low nonlinearity make the AD526 ideal for precision instrumentation applications requiring programmable gain.
