LQFP (PZA)-80-256 mm² 16 x 16

The ADS8686S is a 16-channel data acquisition (DAQ) system based on a dual simultaneous-sampling, 16-bit successive approximation register (SAR) analog-to-digital converter (ADC). The ADS8686S features a complete analog front-end for each channel with an input clamp, 1-MΩ input impedance, independently programmable gain amplifier (PGA), programmable low-pass filter, and an ADC input driver. The device also features a low-drift, precision reference with a buffer to drive the ADCs. A flexible digital interface supporting serial, parallel, and byte communication enables the device to be used with a variety of host controllers.

The ADS8686S can be configured to accept ±10-V, ±5-V, or ±2.5-V bipolar inputs with a 20% overrange option using a single 5-V supply. The high input impedance allows direct connection with sensors and transformers, thus eliminating the need for external driver circuits. The ADS8686S has a highly configurable channel sequencer to reduce the sequencing overhead on the backend controller or processor. The high performance and accuracy, along with zero-latency conversions offered by this device make the ADS8686S a great choice for multiple industrial applications.
