ADS574JE

Analog To Digital Converters (ADC) Overview

The ADS574JE is a 12-bit successive approximation analog-to-digital converter (ADC) manufactured by Texas Instruments. It integrates a sampling A/D with an internal reference, clock, and microprocessor interface. The device operates from a single +5V supply and dissipates a maximum of 100mW. Key electrical parameters include a maximum conversion time of 25μs for a 12-bit cycle, a sampling rate of 40kHz, and a spurious-free dynamic range of 73dB to 76dB. It features three-state outputs and supports input voltage ranges of 0V to +10V, 0V to +20V, ±5V, or ±10V.

Analog To Digital Converters (ADC) Feature Summary

• Complete 12-bit ADC with internal sampling, reference, and microprocessor interface
• Single +5V supply operation with low power consumption (max 100mW)
• Fast acquisition and conversion with a maximum throughput time of 25μs
• Eliminates external sample/hold amplifiers in most applications via internal S/H

Analog To Digital Converters (ADC) Applications

• Microprocessor-based data acquisition systems
• Industrial process control instrumentation
• Battery-powered measurement devices requiring low power
• Replacement for legacy ADC574 designs

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific package variant required, as the JE suffix denotes a 0.3-inch Plastic DIP. Confirm that the design utilizes the S/H Control Mode (Pin 11 to +5V) or Emulation Mode (Pin 11 to VEE/Ground) to ensure correct timing behavior. Check for RoHS compliance status if manufacturing in restricted regions, as this is a legacy component.

Analog To Digital Converters (ADC) Selection Notes

Select the ADS574JE when a drop-in replacement for the ADC574 is needed with lower power consumption. Ensure the application can accommodate the 40kHz sampling rate and 25μs conversion latency. Verify that the input signal ranges match the internal scaling resistors for 0-10V, 0-20V, ±5V, or ±10V inputs without external attenuation.

Analog To Digital Converters (ADC) Part Context

The ADS574 series serves as a modernized successor to the Burr-Brown ADC574. While maintaining pin compatibility for socket replacement, it offers improved power efficiency and integrated functionality. The JE variant specifically refers to the commercial temperature grade (0°C to +70°C) housed in a narrow 0.3-inch DIP package.
