ADS1243 Description

Short technical summary and product information.

The Texas Instruments ADS1243 is a precision, wide dynamic range, delta-sigma analog-to-digital converter with 24-bit resolution. It operates from a 2.7-V to 5.25-V supply range and offers up to 24 bits of no missing code performance with an effective resolution of 21 bits. The device supports simultaneous 50-Hz and 60-Hz rejection with a minimum of -90 dB.

 

Key features include a programmable gain amplifier (PGA) with gains from 1 to 128, an integral non-linearity (INL) of 0.0025%, and an external differential reference range of 0.1 V to 5 V. It provides up to eight input channels and an SPI-compatible serial interface. The ADS1243 is designed for applications requiring high precision in challenging environments.

 

This ADC is available in a TSSOP (PW) package with dimensions of 6.5 mm x 6.4 mm. It operates within an extended temperature range of -40°C to 85°C and has a typical power consumption of 0.6 mW.
