描述The ADS7841 is a 4-channel, 12-bit sampling Analog-to-Digital Converter (ADC) with a synchronous serial interface. The resolution is programmable to either 8 bits or 12 bits. Typical power dissipation is 2mW at a 200kHz through-put rate and a +5V supply. The reference voltage (VREF) can be varied between 100mV and VCC, providing a corresponding input voltage range of 0V to VREF. The device includes a shutdown mode which reduces power dissipation to under 15uW. The ADS7841 is tested down to 2.7V operation. Low power, high speed, and on-board multiplexer make the ADS7841 ideal for battery-operated systems such as personal digital assistants, portable multi-channel data loggers, and measurement equipment. The serial interface also provides low-cost isolation for remote data acquisition. The ADS7841 is available in a DIP-16 or a SSOP-16 package and is specified over the \x9640°C to +125°C (1) temperature range.特性SINGLE SUPPLY: 2.7V to 5V 4-CHANNEL SINGLE-ENDED OR 2-CHANNEL DIFFERENTIAL INPUT UP TO 200kHz CONVERSION RATE ±1LSB MAX INL AND DNL NO MISSING CODES 72dB SINAD SERIAL INTERFACE DIP-16 OR SSOP-16 PACKAGE ALTERNATE SOURCE FOR MAX1247 ADS7841ES: +125°C Version APPLICATIONS DATA ACQUISITION TEST AND MEASUREMENT INDUSTRIAL PROCESS CONTROL PERSONAL DIGITAL ASSISTANTS BATTERY-POWERED SYSTEMSNOTE: (1) ES grade only.
