3 Description
The PGA855 is a high-bandwidth programmable
gain instrumentation amplifier with fully differential
outputs. The PGA855 is equipped with eight binary
gain settings, from an attenuating gain of 0.125 V/V
to a maximum of 16 V/V, using three digital gain
selection pins. The output common-mode voltage can
be independently set using the VOCM pin.
The PGA855 architecture is optimized to drive
inputs of high-resolution, precision analog-to-digital
converters (ADCs) with sampling rates up to 1 MSPS
without the need for an additional ADC driver. The
output-stage power supplies are decoupled from the
input stage to protect the ADC or downstream device
against overdrive damage.
The super-beta input transistors offer an impressively
low input bias current, which in turn provides a
very low input current noise density of 0.3 pA/√Hz,
making the PGA855 a versatile choice for virtually
any sensor type. The low-noise current-feedback
front-end architecture offers excellent gain flatness
even at high frequencies, making the PGA855 an
excellent high-impedance sensor readout device.
Integrated protection circuitry on the input pins
handles overvoltages up to ±40 V beyond the powersupply
voltages.
