ADS7042IDCUR

Analog To Digital Converters (ADC) Overview

The ADS7042IDCUR is a single-channel, 12-bit Successive Approximation Register (SAR) Analog-to-Digital Converter manufactured by Texas Instruments. It operates with a sampling rate of 1 MSPS and supports an analog supply voltage range of 1.65 V to 3.6 V. The device features a single-ended input configuration and communicates via a standard SPI interface. It is housed in an 8-pin Very Small Size Outline Package (VSSOP) with a pitch of 0.5 mm. The component is rated for operation within a temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrated sample-and-hold function simplifies front-end driver requirements.

Analog To Digital Converters (ADC) Applications

• Portable medical instrumentation
• Battery-powered sensor nodes
• Industrial process control systems

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IDCUR against the manufacturer's official datasheet to confirm package dimensions and tape-and-reel specifications. Ensure compatibility with the target system's voltage levels and communication protocol before integration. Cross-reference the ordering part number with the latest revision history to avoid discrepancies in electrical characteristics or pinout definitions.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance of moderate resolution and high speed is required in a constrained physical space. The single-ended input type dictates signal conditioning strategies different from fully differential counterparts. Consider the 1.65 V minimum supply voltage when designing power rails for low-voltage microcontroller interfaces.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADS704x family of ultra-low-power SAR ADCs. It shares architectural similarities with the ADS7040 and ADS7044 but offers distinct resolution and input configuration options. The family emphasizes miniaturization and energy efficiency for modern embedded sensing applications.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7042IDCUT serves as a cut-tape alternative to the reel-packaged IDCUR variant. Verify that the functional specifications remain identical between packaging types before substitution.
