TI ADS7843E/2K5

4 线电阻式12 b串行2.7V ~ 5V-40°C ~ 85°C

Overview

The ADS7843E/2K5 is a 12-bit sampling Analog-to-Digital Converter (ADC) with a synchronous serial interface and low onresistance switches for driving touch screens. Typical power dissipation is 750µW at a 125kHz throughput rate and a +2.7V supply. The reference voltage (VREF) can be varied between 1V and +VCC, providing a corresponding input voltage range of 0V to VREF. The device includes a shutdown mode which reduces typical power dissipation to under 0.5µW. The ADS7843E/2K5 is specified down to 2.7V operation. Low power, high speed, and onboard switches make the ADS7843E/2K5 ideal for battery-operated systems such as personal digital assistants with resistive touch screens and other portable equipment. The ADS7843E/2K5 is available in an SSOP-16 package and is specified over the –40°C to +85°C temperature range.
