ADC10040CIMT/NOPB

Analog To Digital Converters (ADC) Overview

The ADC10040CIMT/NOPB is a monolithic CMOS analog-to-digital converter featuring a 10-bit resolution and a conversion rate of 40 MSPS. It utilizes 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, and includes an internal 1.2V reference. It supports selectable input swings of 2.0 VP-P, 1.5 VP-P, or 1.0 VP-P via the IRS pin. The component is housed in a 28-lead TSSOP package and functions within an industrial temperature range of −40°C to +85°C.

• xDSL and Wireless Local Loops

Analog To Digital Converters (ADC) Procurement Notes

Verify that the ordering suffix 'NOPB' indicates a lead-free (RoHS compliant) version of the standard ADC10040CIMT part. Confirm the specific package variant matches the required PCB footprint, as the base model may be available in other packages such as the 28-pin SSOP. Ensure the supplier provides documentation confirming the absence of halogenated compounds if strict environmental compliance is required.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a low-power, single-supply 10-bit ADC is required for mid-speed signal processing. The device accommodates both 2.5V and 3.3V logic families through its adjustable output driver supply (VDDIO). Designers must ensure the analog supply (VDDA) and digital supply (VDDIO) are closely matched, with a maximum difference of 100 mV, to maintain accuracy and prevent latch-up conditions during operation.

Analog To Digital Converters (ADC) Part Context

This part belongs to the Texas Instruments ADC10040 family, which also includes the automotive-grade ADC10040Q. The CIMT/NOPB designation specifically identifies the commercial temperature grade (-40°C to +85°C), the TSSOP-28 package, and the lead-free finish. It serves as the standard industrial alternative to the qualified automotive version for general-purpose data acquisition and communication receiver front ends.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC10040CIMT/NOPB is functionally equivalent to the non-NOPB version (ADC10040CIMT), differing only in packaging material specifications regarding lead content. No direct cross-manufacturer replacements are documented in the provided source material.
