AD7997 - 10- and 12-Bit ADCs

General Description

The AD7997/AD7998 are 8-channel, 10- and 12-bit, low power, successive approximation ADCs with an I2C-compatible interface.

The parts operate from a single 2.7 V to 5.5 V power supply and feature a 2 µs conversion time.

Key Features

  • 10- and 12-bit ADC with fast conversion time: 2 µs typ 8 single-ended analog input channels Specified for VDD of 2.7 V to 5.5 V Low power consumption Fast throughput rate: up to 188 kSPS Sequencer operation Automatic cycle mode I2C®-compatible serial interface supports standard, fast, and high speed modes Out-of-range indicator/alert function Pin-selectable addressing via AS Shutdown mode: 1 µA max Temperature range:.
  • 40°C to +85°C 20-lead TSSOP package See the AD7992 and AD7994 for 2-ch.
