12-BIT ANALOG-TO-DIGITAL CONVERTERS PROVIDE SOFTWARE CONFIGURABILITY AND LOW POWER

• Throughput Rate, 222KHz
• Low Power Dissipation, 34mW (max)
• Micropower Standby Mode for Portable Systems, 75microW (max)
• Zero Glue Logic Interface to Popular Microprocessors

SANTA CLARA, CALIF., - September 19, 1995 - Addressing the high-speed, low-power needs of process control systems, data acquisition boards, and test and measurement applications, National Semiconductor has introduced two 12-bit plus sign, parallel I/O, sampling analog- to-digital converters. The ADC12041, with single channel differential input, and the ADC12048, with an eight channel multiplexer, can both be interfaced with many popular 8-bit and 16-bit microprocessors with zero glue logic. Both devices operate at a throughput rate of 222KHz, while maintaining power dissipation at a low 34mW.

The converters also offer a high level of programmable features, making them adaptable to various applications. Programmable acquisition times, user-controllable throughput rates and data bus width (8/13 bits) coupled with Auto-Calibration and Auto-Zero cycles make the ADC12041 and ADC12048 flexible and user friendly. Both devices also offer the option of a user-programmable stand-by mode that lowers power consumption to 75microW (max).

National also offers a detailed information packet and a complete design kit for quick, easy evaluation of the product at the bench. The ADC12048EVAL design kit includes an evaluation board, which can be used with either portable or desktop PCs and plugs into a PC-compatible serial port, and the powerful new WaveVision demonstration and evaluation software. Evaluation software is a complete product demonstration and design tool that familiarizes the designer with operation of the ADC12048CIV, and allows the designer to program and operate the evaluation board for design verification.
