Overview
The ADS1253E is a low-power, 24-bit analog-to-digital converter (ADC) manufactured by Burr-Brown (Texas Instruments). It features an on-chip programmable gain amplifier (PGA) with gains of 1, 2, 4, 8, 16, 32, and 64. The device operates from a single 2.7V to 5.5V supply and includes an internal oscillator. Key specifications include a data rate up to 40kSPS, a noise-free resolution of 19 bits at 60Hz, and a serial interface compatible with standard SPI. It is housed in a small 16-pin TSSOP package.
Feature Summary
- 24-bit resolution with 19 bits noise-free at 60Hz
- On-chip PGA with gains from 1 to 64
- Low power consumption: 3.5mA at 40kSPS
- Internal oscillator and reference input
Applications
- Industrial process control
- Medical equipment
- Weight scales and load cells
- Portable instrumentation
Procurement Notes
Verify the specific suffix 'E' indicates the lead-free RoHS-compliant version. Confirm the package type is TSSOP-16. Check for availability of the industrial temperature grade variant if required for extreme environments. Ensure the supplier provides the official datasheet for pinout and electrical characteristics verification.
Selection Notes
Select this component when high-resolution ADC performance is needed with minimal external components. The integrated PGA reduces the need for external amplifiers. Consider the 40kSPS maximum data rate for speed requirements. Compare with ADS1252 or ADS1256 if different channel counts or data rates are necessary.
Part Context
The ADS1253 is part of the ADS125x family of 24-bit ADCs. It shares architectural similarities with the ADS1252 and ADS1256 but differs in channel count and specific feature sets. It is designed for applications requiring precise measurement of low-level signals from sensors like strain gauges and thermocouples.
Replacement Considerations
ADS1252: Fewer channels, similar performance. ADS1256: More channels, higher data rate. ADS1255: Similar specs, different package options. Verify pin compatibility and software register settings before substitution.
