SPI Programmable-Gain Amplifier

Maxim Integrated
Differential-Input, Differential-Output PGA
The output amplifier can be configured so that the
MAX9939 operates as a differential-input, differential-
output programmable gain amplifier. As shown in
Figure 4, use a 10k
resistor between OUTA and INB,
and between INB and OUTB. Such a differential-output
configuration is ideal for use in low-voltage applications
that can benefit from the 2X output voltage dynamic
range when compared to single-ended output format.
Use of Output Operational Amplifier as TIA
CMOS inputs on the output op amp makes it ideal for
use as an input transimpedance amplifier (TIA) in cer-
tain current-output sensor applications. In such a situ-
ation, keep in mind that the inverting input operates at
fixed voltage of VCC/2. Use a high-value resistor as a
feedback gain element, and use a feedback capacitor
in parallel with this resistor if necessary to aid amplifi-
er stability in the presence of high photodiode or
cable capacitance. The output of this TIA can be rout-
ed to INA+ or INA- for further processing and signal
amplification.
Power-Supply Bypassing
Bypass VCC to GND with a 0.1F capacitor in parallel
with a 1F low-ESR capacitor placed as close as possi-
ble to the MAX9939.
