TI Introduces Industry's Smallest Four-Channel, 24-Bit Data Converter

Low-Power, Easy-to-Use ADC Targets Portable Measurement Applications

Jun 10, 2004

DALLAS (June 10, 2004) - Texas Instruments Incorporated (TI) (NYSE: TXN) today introduced the industry´s smallest four-channel, 24-bit delta-sigma analog-to-digital converter (ADC) from the company´s Burr-Brown product line. Packaged in a small TSSOP-20 and consuming only 300uA of current, this easy-to-use data converter is designed for high-resolution measurement applications where space and power consumption are critical, such as portable instrumentation, portable medical equipment, industrial process control, remote sensors, smart transmitters and weigh scales.

"The ADS1224 delivers excellent performance at 240SPS data rate, low power and wide dynamic range in a miniature TSSOP package. This unmatched combination of performance, flexibility and size provides customers with a high-performance industrial ADC specifically designed for demanding measurements in portable and power-constrained applications," said Jim Todsen, product line manager for TI's oversampling data converters.
The ADS1224 includes a four-channel differential input multiplexer, which accepts rail-to-rail inputs and features a temperature sensor for ambient temperature measurement. The optional input buffer allows the direct connection to high-impedance sensors without bias current errors. Dedicated I/O pins directly control the input multiplexer, temperature sensor and input buffer, eliminating the need for onboard control registers.
The ADS1224 quickly shuts down (standby mode) while idle between measurements to dramatically reduce the overall power consumption (
