That 40 kSPS rate means it captures one 16-bit conversion every 25 µs — fast enough to digitise a 2 kHz audio band with headroom for anti-alias filter roll-off, or to oversample a dozen slow sensor channels in a round-robin scan. The single-ended input and 1:1 S/H:ADC ratio mean one sample-and-hold feeds one converter — no mux settling delay between channels. For a single-channel data-acquisition path, this eliminates the timing uncertainty a multiplexed front-end introduces. ## SPI and parallel interface — which one to use The ADS8507IDW offers both SPI and parallel data interfaces. The parallel bus gives you a full 16-bit read in one cycle — useful when the host controller has a free parallel port and you need deterministic read timing. The SPI interface saves pins on the controller side and isolates the ADC from the digital noise on a wide bus. Both digital and analog supply rails run at 5 V, so the digital I/O levels match a 5 V logic bus directly. If the host runs at 3.3 V, a level translator sits between the ADC and the controller. ## Industrial temperature range and package Housed in a 28-SOIC wide-body (7.50 mm width) package, the part is surface-mount with a 1.27 mm pitch — a standard footprint that routes easily on a two-layer board. The tube packaging suits prototype and low-volume production runs.","metaTitle":"ADS8507IDW 16-bit SAR ADC, 40 kSPS, 28-SOIC","metaDescription":"Texas Instruments ADS8507IDW 16-bit SAR ADC, 40 kSPS sampling rate, single-ended input, SPI/parallel interface, 28-SOIC package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Tube","Input Type":"Single Ended","Architecture":"SAR","Configuration":"S/H-ADC","Mounting Type":"Surface Mount","Data Interface":"SPI, Parallel","Number of Bits":"16","Package / Case":"28-SOIC (0.295\\\", 7.50mm Width)","Reference Type":"External, Internal","Ratio - S/H:ADC":"1:1","lifecycle_stage":"eol_hot","Number of Inputs":"1","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"28-SOIC","Number of A/D Converters":"1","Voltage - Supply, Analog":"5V","Voltage - Supply, Digital":"5V","Sampling Rate (Per Second)":"40k"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$17.66","priceTiers":[{"qty":1,"price":"$17.66000","currency":"USD"},{"qty":10,"price":"$16.22900","currency":"USD"},{"qty":25,"price":"$15.55680","currency":"USD"},{"qty":100,"price":"$13.70660","currency":"USD"},{"qty":250,"price":"$13.03392","currency":"USD"},{"qty":500,"price":"$12.19302","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/dd8d3cd58a68b972885285ebf2240635.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/ADS8507IDW/alternatives.json"},"ai":{"faq":[{"question":"What is the sampling rate and resolution of the ADS8507IDW?","answer":"The ADS8507IDW samples at 40 kSPS with 16-bit resolution.
