New from Texas Instruments is the PGA11x family of zero-drift programmable gain amplifiers (PGA) with single-ended input, single-supply operation, rail-to-rail I/O and multichannel multiplexers (MUX). The PGA112, PGA113, PGA116 and PGA117 provide a flexible, highly integrated programmable gain amplification solution for microprocessor-based applications such as portable data acquisition, remote meter reading, automatic gain control, programmable logic controllers and handheld test equipment.
The PGA112 and PGA116 offer binary gains of 1, 2, 4, 8, 16, 64, and 128 while the PGA113 and PGA117 have scope gains of 1, 2, 5, 10, 20, 50, 100 and 200. In addition to eliminating the need for matched discrete components, the PGA11x family includes the added benefits of multichannel MUXs, calibration and digitally controlled gain.
The PGA112 and PGA113 have a two-channel MUX, and the PGA116 and PGA117 have a 10-channel MUX. The op-amp output stage can be powered by the same power supply as the ADC, which is useful in multisupply systems to prevent an over-voltage/lockup condition on an ADC input.
The PGA11x family provides internal calibration channels for system-level calibration. Gain switching time is 200 ns and gain settling is 2,55 μs at 0,01%. For all of the devices, DC gain error is 0,1% (max with G less than or equal to 32) over temperature. All devices use a standard SPI serial interface with daisy-chain capability.
Other highlights include an offset of 100 μV and an offset drift of 1,2 μV/C, low noise (12 nV/rtHz typical) and wide bandwidth (10 MHz in G=1). In addition, the devices feature low input on-channel current (5 nA max) and shutdown that can achieve a supply current of less than 4 μA. The devices are also specified over an extended temperature range of -40°C to +125°C.
