PGA112AIDGST Datasheet PDF - TI

●The PGA112AIDGST is a zero-drift Programmable Gain Amplifier with MUX function. This device (binary and scope gains) offers two analog inputs, a three-pin SPI interface and software shutdown. It provides internal calibration channels for system-level calibration. The channels are tied to GND, 0.9 VCAL, 0.1 VCAL and VREF, respectively. VCAL, an external voltage connected to Channel 0, is used as the system calibration reference.

● Rail-to-rail input and output

● Four internal calibration channels

● Amplifier optimized for driving CDAC ADCs

● SPI™ interface (10MHz) with daisy-chain capability

● 50mV to supply rails Output swing

● 12nV/√Hz Low noise

● ±5nA (25°C) Maximum input offset current

● 200ns Gain switching time

● Green product and no Sb/Br
