3 Description

The ADS9308V8I is a 16-channel, 24-bit successive approximation (SAR) analog-to-digital converter (ADC) with integrated analog front end for simultaneous current and voltage sensing. The device integrates eight zero-drift programmable gain amplifiers for current sensing, and eight low-drift programmable gain difference amplifiers for voltage sensing. The ADC inputs can be directly connected to the power supply to measure voltage and current simultaneously. The device delivers a maximum throughput of 125kSPS on each channel. The device also features a low-drift, precision reference with a buffer to drive the ADC.

The ADS9308V8I includes a flexible digital interface, allowing the device to be used with a variety of host controllers. Users can configure the serial interface to read the ADC output on 1-lane, 2-lane, 4-lane, and 8-lane. The device also has flexibility to operate the ADC as 2-CH, 4-CH, 8-CH and 16-CH simultaneous sampling ADC.
