The ADS8867IDGSR is a 16-bit, 100-kSPS, true-differential input SAR analog-to-digital converter from Texas Instruments, engineered for precision data acquisition in space-constrained, battery-powered systems. Operating with a 2.5V to 5V external reference that is independent of, and can exceed, the analog supply voltage (AVDD), this microPower ADC supports unipolar true-differential analog input signals swinging from -VREF to +VREF with a wide common-mode voltage range of 0V to VREF and 90dB minimum common-mode rejection.
The SAR ADC delivers excellent AC and DC performance with 96dB SNR, -115dB THD, and maximum INL/DNL of ±1.0 LSB with no missing codes. Consuming only 0.7mW at 100kSPS and featuring a no-latency output with SPI-compatible serial interface supporting daisy-chain operation, the ADS8867 ships in a compact 10-pin VSSOP (DGSR) package with tape-and-reel packing, operating across a -40°C to +85°C industrial temperature range.
Applications
● Battery-powered data acquisition systems and portable instrumentation requiring microPower consumption.
● Industrial process control and automation with differential sensor signal conditioning.
● Medical instrumentation and patient monitoring equipment demanding high-precision, low-noise conversion.
● Multichannel data acquisition modules using the daisy-chain SPI capability.
● Test and measurement equipment requiring true-differential inputs with wide common-mode rejection.
● Transducer direct-connection interfaces in remote monitoring and IoT sensor nodes.
FAQs
Q: How does the ADS8867 differ from the ADS8866? A: The ADS8867 features true-differential inputs accepting -VREF to +VREF signals, while the ADS8866 is a single-ended input variant accepting 0 to +VREF with slightly lower SNR (93dB vs 96dB).
Q: Can the reference voltage exceed the analog supply? A: Yes - the REF input range of 2.5V to 5V is independent of AVDD, so a 5V reference can be used with a 3.3V analog supply.
Q: What is the power consumption? A: The device dissipates only 0.7mW at the full 100kSPS rate, dropping to 70µW at 10kSPS, with just 50nA power-down current.
Alternative SAR ADC Models
● ADS8887IDGSR: The 18-bit, 100kSPS upgrade delivering higher resolution with the same true-differential architecture for precision-critical applications.
● ADS8861IDGS: The 16-bit, 1MSPS faster variant in the same family for high-speed differential acquisition up to 10x the throughput.
● ADS8339: A 16-bit, 250kSPS single-ended ADC with wider 2.25V to 5.5V reference range for moderate-speed unipolar designs.
● ADS8688: An 8-channel, bipolar-input SAR ADC with integrated reference and wide input ranges for multi-channel industrial systems.
● ADS8881: The 18-bit, 1MSPS flagship with 100dB SNR for ultra-high-resolution, high-speed differential measurements.
