3 Description
The PGA849 is a wide-bandwidth, low-noise
programmable gain instrumentation amplifier for
differential-to-single-ended conversion. The PGA849
is equipped with eight binary gain settings, from an
attenuating gain of 0.125V/V to a maximum of 16V/V,
using three digital gain selection pins.
The PGA849 architecture is optimized to drive
inputs of high-resolution, precision analog-to-digital
converters (ADCs) with sampling rates up to 1MSPS
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 0.3pA/√Hz,
making the PGA849 a versatile choice for virtually
any sensor type. The low-noise current-feedback
front-end architecture offers exceptional gain flatness
even at high frequencies, making the PGA849 an
excellent high-impedance sensor readout device.
Integrated protection circuitry on the input pins
handles overvoltages of up to ±40V beyond the
power-supply voltages.
