The instrumentation amplifier provides digitally or pin-programmable gains of 1, 2, 4, and 8 with a 2-bit parallel gain interface. It operates from ±5 V to ±15 V supplies and is specified from −40°C to +85°C in a 10-lead MSOP package. The amplifier supports 10 MHz small-signal bandwidth at G = 1, 20 V/µs minimum slew rate, −110 dB THD+N, and 785 ns maximum settling to 0.001%. Precision performance includes 98 dB minimum CMRR at G = 8, 10 ppm/°C maximum gain drift, and 1.8 µV/°C maximum offset drift at G = 8.
