ADS774KP-4

Analog To Digital Converters (ADC) Overview

The ADS774KP-4 is a high-speed, 12-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a sampling rate of 1 MSPS and utilizes a successive approximation register (SAR) architecture. The device operates with a single +5V power supply and includes an internal voltage reference. It offers a throughput of 1 MSPS with a conversion time of 1 µs. The input range is typically 0 to VREF. The component is housed in a 28-pin plastic small-outline package (SOIC).

Analog To Digital Converters (ADC) Feature Summary

• High-speed 1 MSPS sampling capability for real-time data acquisition.
• Integrated internal voltage reference reduces external component count.
• Single +5V supply operation simplifies power design.
• Microprocessor-compatible parallel interface for easy system integration.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring fast signal digitization.
• Medical instrumentation such as ultrasound and ECG devices.
• Data acquisition systems in automated test equipment.
• Communication infrastructure signal processing.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'KP-4' against official Texas Instruments documentation to confirm pinout, temperature range, and packaging details. Ensure compatibility with existing board layouts and power supplies. Check for current availability status as older SAR ADC models may have limited production runs or obsolescence notices. Confirm RoHS compliance if required for your region.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance of speed and resolution is needed without external reference requirements. Consider the parallel interface complexity versus serial alternatives like SPI. Evaluate power consumption at full 1 MSPS rate against thermal constraints. Compare performance metrics such as SNR and THD against newer integrated solutions if size or cost is critical.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS77x family of high-speed ADCs from Texas Instruments. These devices are designed for applications demanding moderate resolution with high throughput. The family typically shares similar architectural features but varies in channel count and interface types. This specific model represents a legacy option in TI's data converter portfolio.

Analog To Digital Converters (ADC) Replacement Considerations

Check for direct pin-to-pin replacements within the ADS774 series or newer iterations like the ADS776x family. Verify that any substitute maintains the 12-bit resolution and 1 MSPS speed. Ensure the replacement supports the same +5V supply and parallel interface protocol to avoid redesigning the host microcontroller connection.
