Tucson, Ariz. Texas Instruments Inc. has rolled out the last in a series of four pin-compatible A/D converters from Burr-Brown. The 16-bit, four-channel ADS8341 joins the 16-bit, eight-channel ADS8344; 12-bit, four-channel ADS7841; and 12-bit, eight-channel ADS7844.
Wayne Talley, strategic marketing engineer of Burr-Brown data converter products, said the four A/Ds make up the only multichannel, pin-compatible family of 12- and 16-bit converters. Pin compatibility makes it possible to replace any of them with any of the others, with no redesign.
The new ADS8341, which packs an on-board multiplexer, operates over a 2.7- to 5-volt power supply range. Conversion is at 100 kHz and power consumption is 8 mW at 100 kHz. Packaged in a 16-pin SSOP, the device has a serial input port said to facilitate interfacing to a microprocessor that can subsequently program the A/D to provide channel selection and single-ended or differential inputs.
Talley said the ADS8341 offers an upgrade to 12-bit products in portable, battery-operated applications such as PDAs, test and measurement equipment, and industrial data acquisition. Power consumption is sufficiently low to extend battery life, he added.
The A/DS8341 is available now, starting at $7 in lots of 1,000.
