Data buffer has dual multiplexer
Texas Instruments has introduced the industry's first 0- to 4-Gbps data buffer/signal conditioner with a dual multiplexer.
"The ADS8342 is the next generation of TI's successful bipolar input ADC family with added benefits such as the lowest offset voltage, no missing codes performance, improved DC specifications and the best price/performance ratio versus competition", said Miroslav Oljaca, Strategic Marketing Manager for TI's motor control convertor products.
The ADS8342 consists of a four-channel input multiplexer, a capacitor-based SAR ADC with inherent sample-and-hold, an interface for microprocessor use, and parallel tristate output drivers.
The SAR architecture and CMOS process allow the ADS8342 to acquire and convert an analogue signal at up to 250,000 conversions per second, while consuming less than 200mW of power.
The device also features 16bit no missing codes, +/-1mV offset voltage, +/-2LSB typical integral nonlinearity (INL) and a selectable 8 or 16bit parallel interface.
The ADS8342 is packaged in a TQFP-48, and is available now from TI and its authorised distributors.
Suggested resale pricing is $10.75 in 1000-piece quantities.
