PGA855 Low-Noise, Wide-Bandwidth, Fully Differential Output Programmable-Gain Instrumentation Amplifier

1 Features

Eight pin-programmable binary gains
- G (V/V) = ⅛, ¼, ½, 1, 2, 4, 8, and 16
Low gain error drift: 1 ppm/°C (max) at G = 1 V/V
Fully differential outputs
- Independent output power-supply pins to allow for ADC input overdrive protection
- Output common-mode control
Faster signal processing:
- Wide bandwidth: 10 MHz at all gains
- High slew rate: 35 V/µs
- Settling time:
  500 ns to 0.01%, 950 ns to 0.0015%
- Input stage noise: 7.8 nV/√Hz at G = 16 V/V
- Filter option to achieve better SNR
Input overvoltage protection to ±40 V beyond supplies
Input-stage supply range:
- Single supply: 8 V to 36 V
- Dual supply: ±4 V to ±18 V
Output-stage supply range:
- Single supply: 4.5 V to 36 V
- Dual supply: ±2.25 V to ±18 V
Specified temperature range: –40°C to +125°C
Small package: 3-mm × 3-mm VQFN
