ADS8344E Overview

ADS8344E is the QSOP-20 (DBQ) tube orderable of TI's ADS8344, an 8-channel, 16-bit sampling analog-to-digital converter with a synchronous serial interface. Searches for the bare 'ADS8344' land here: the bare number is the device name, and TI's orderables are ADS8344E and ADS8344EB (QSOP-20) and ADS8344N and ADS8344NB (SSOP-20 DB), each also on tape and reel. The ADS8344 converts at up to 100 kHz, takes 8 single-ended or 4 differential inputs referenced to a 500 mV to VCC external reference, dissipates 10 mW typical at 100 kHz and 5 V and drops below 15 µW in shutdown. It runs from 2.7 V to 5 V over -40 °C to +85 °C and is pin-for-pin with the 12-bit ADS7844. TI lists the ADS8344 and the ADS8344E orderable as Active.

Key Features

  • 16-bit, 100 kSPS SAR ADC
  • 8-channel single-ended or 4-channel differential multiplexer
  • Synchronous serial interface; DCLK = 24 x sample rate
  • Single supply 2.7 V to 5 V; shutdown under 15 µW
  • External reference 500 mV to VCC
  • Pin-for-pin with ADS7844 (12-bit)

Applications

  • Data acquisition
  • Test and measurement equipment
  • Industrial process control
  • Battery-powered and portable multi-channel loggers
