ADC10040CIMT

Analog To Digital Converters (ADC) Overview

The ADC10040CIMT is a monolithic CMOS analog-to-digital converter manufactured by Texas Instruments. It provides 10-bit resolution at a sampling rate of 40 MSPS using a differential pipeline architecture with digital error correction and an on-chip sample-and-hold circuit. The device operates on a single +3.0V supply, consuming 55.5 mW at full speed. It features selectable full-scale input swings of 2.0 VP-P, 1.5 VP-P, or 1.0 VP-P via the IRS pin. The ADC10040CIMT is housed in a 28-lead TSSOP package and supports industrial operating temperatures from -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

Analog To Digital Converters (ADC) Procurement Notes

Verify that the component matches the specific ordering suffix CIMT for the 28-TSSOP package variant. Confirm the revision level against the SNAS224M datasheet dated April 2013. Ensure the application environment remains within the specified -40°C to +85°C temperature range. Check for AEC-Q100 Grade 3 qualification if automotive compliance is required, noting that the CIMT suffix denotes the standard industrial grade.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a high-speed 10-bit conversion is required with low power constraints. The ADC10040CIMT requires a single +3.0V analog supply and a separate digital I/O supply between 2.5V and VDDA. Designers must account for a 6-cycle pipeline latency and ensure proper clock duty cycle maintenance (30% to 70%) to preserve dynamic performance. Use the IRS pin to configure the input range based on the signal amplitude requirements.

Analog To Digital Converters (ADC) Part Context

The ADC10040CIMT belongs to the ADC10040 family of high-speed analog-to-digital converters. This series utilizes a proprietary differential pipeline process optimized for low power and high dynamic performance. The CIMT designation specifically identifies the industrial temperature grade version packaged in a 28-pin Thin Shrink Small Outline Package (TSSOP).
