ADS901E/1K

Analog To Digital Converters (ADC) Overview

The ADS901E/1K is a high-speed pipelined analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a 10-bit resolution and supports sampling rates up to 20 MSPS. The device operates from a single +3V supply, with a specified range of +2.7V to +3.7V. It consumes low power, typically around 48mW at the nominal supply voltage. The ADC includes an internal sample-and-hold amplifier and offers adjustable full-scale input ranges via external references. It is available in a 28-pin SSOP package and is designed for applications requiring precision data acquisition without missing codes.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix '1K' indicates tape and reel packaging when sourcing. Confirm the operating temperature range meets application requirements, as industrial grades may differ. Ensure external reference components are compatible with the adjustable full-scale input specifications. Cross-check pinout compatibility if replacing existing designs. Validate supply voltage stability within the +2.7V to +3.7V window for optimal performance.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring moderate resolution with high throughput under low power constraints. The single-supply operation simplifies board design compared to dual-rail solutions. Consider the external reference requirement when budgeting for additional passive components. The 28-SSOP package suits space-constrained designs but requires appropriate thermal management during soldering. Evaluate system noise floors against the ADC's dynamic performance specifications.

Analog To Digital Converters (ADC) Part Context

The ADS901 series represents Texas Instruments' SpeedPlus family of analog-to-digital converters. These devices bridge the gap between low-speed sigma-delta ADCs and high-speed flash converters. The ADS901E/1K variant specifically denotes the commercial grade version supplied in tape and reel format. This series is engineered for cost-sensitive applications demanding reliable performance without excessive power draw.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes include other 10-bit, 20 MSPS pipelined ADCs from Texas Instruments such as the ADS900 series. Verify pinout compatibility before swapping packages. Check if alternative parts require different reference configurations or supply voltage levels. Ensure equivalent spurious-free dynamic range and signal-to-noise ratio metrics match system requirements.
