Features
Differential to single-ended conversion
Eight pin-programmable binary gains
G (V/V) = ⅛, ¼, ½, 1, 2, 4, 8, and 16
Low gain error drift: ±2ppm/°C (maximum)
Faster signal processing:
Wide bandwidth: 10MHz at all gains
High slew rate: 35V/µs at G ≥ ½ V/V
Settling time:
700ns to 0.01%, 950ns to 0.0015%
Input stage noise: 8.6nV/√
Hz
at G = 16V/V
Filter option to achieve better SNR
Input overvoltage protection to ±40V beyond supplies
Input-stage supply range:
Single supply: 8V to 36V
Dual supply: ±4V to ±18V
Independent output power-supply pins
Output-stage supply range:
Single supply: 4.5V to 36V
Dual supply: ±2.25V to ±18V
Specified temperature range: –40°C to +125°C
Small package: 3mm × 3mm QFN
