ADS8668IDBT

Description

The Texas Instruments ADS8668IDBT is an 8-channel, single ADC SAR (Successive Approximation Register) with a resolution of 12 bits and a sampling rate of 500 kSPS (samples per second). It features a channel-independent programmable input range of ±10.24 V to ±0.64 V, making it suitable for various industrial automation, process control, motor control, and power monitoring applications. The ADC also includes an on-chip reference with low drift, excellent performance, and low power consumption. The device operates from a 5-V analog supply and has a temperature range of -40°C to 125°C. It is available in a TSSOP-38 package.
