That 860 SPS is the output data rate — the modulator runs faster and the digital filter decimates to 860. For a sigma-delta, the effective number of bits (ENOB) climbs as you drop the data rate; at 860 SPS you get the full 16-bit resolution, but if you need 16-bit settling on a multiplexed channel, budget the filter settling time between mux switches. ## MUX-PGA-ADC chain — no external signal conditioning needed The front-end is a 2-channel differential or 4-channel single-ended mux feeding a programmable gain amplifier (PGA) and then the sigma-delta modulator. The PGA allows full-scale ranges from ±256 mV to ±6.144 V, letting you digitise small sensor outputs (thermocouples, strain gauges) without an external op-amp. The on-chip temperature sensor uses the same ADC core and reports the die temperature — useful for cold-junction compensation or ambient monitoring. The internal voltage reference (2.048 V nominal) eliminates the external reference IC, saving board space and BOM cost. ## Active production — sourced per BOM quantity No official second-source or pin-compatible alternate is listed in the TI documentation; the ADS1118 family shares the same base die but package and temperature grade vary by suffix.","metaTitle":"ADS1118IDGST 16-bit Sigma-Delta ADC, SPI, 860 SPS, PGA","metaDescription":"Texas Instruments ADS1118IDGST 16-bit ADC with PGA, internal reference, and temperature sensor.

The sensor uses the same sigma-delta ADC to digitise the die temperature, which can be read via the SPI interface. This is useful for cold-junction compensation in thermocouple applications or for monitoring ambient temperature near the ADC."},{"question":"What is the SPI mode for ADS1118?","answer":"The ADS1118 uses SPI mode 1 (CPOL=0, CPHA=1) — data is latched on the rising edge of the clock after the first edge. The datasheet specifies the exact timing parameters for the clock frequency and setup/hold times. Ensure your SPI master is configured for mode 1 before attempting communication."},{"question":"Does ADS1118IDGST have an internal reference?","answer":"Yes, it has an internal voltage reference. The reference voltage is 2.048 V nominal, and it is used by the ADC for all conversions."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/ADS1118IDGST","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/ADS1118IDGST when reusing this data.
