The ADS8678IDBTR is a 14-bit, 500-kSPS successive-approximation-register (SAR) analog-to-digital converter from Texas Instruments. It integrates an 8-channel multiplexer with channel-independent programmable input ranges, enabling bipolar inputs from ±10.24 V down to ±0.64 V and unipolar inputs up to 10.24 V.
Key specifications include a maximum sampling rate of 500 kSPS, SPI-compatible interface, and an on-chip 4.096-V reference. The device offers typical SNR of 85 dB, THD of –100 dB, DNL of ±0.2 LSB, and INL of ±0.25 LSB, while consuming only 65 mW. A built-in programmable gain amplifier and oscillator simplify system design.
The ADS8678IDBTR features 1-MΩ constant resistive input impedance and input overvoltage protection up to ±20 V, reducing external protection circuitry. The SPI interface is daisy-chainable to support multiple ADCs in a system. It operates from a 5-V analog supply and a 1.65-V to 5-V digital I/O supply, and is rated for industrial temperature range from –40°C to 125°C. The device is supplied in a 38-pin TSSOP surface-mount package.
