Product Overview

AD7997 is an 8-channel, low power, successive approximation ADC with an I²C-compatible interface. It provides a 2-wire serial interface that is compatible with I²C interface. This device normally remain in a shutdown state while not converting, and power up only for conversions. The conversion process can be controlled using the CONVST pin, by a command mode where conversions occur across I²C write operations or an automatic conversion interval mode selected through software control. On-chip limit registers can be programmed with high and low limits for the conversion result, and an open-drain, out-of range indicator output (ALERT) becomes active when the programmed high or low limits are violated by the conversion result. This output can be used as an interrupt.
  • Conversion time is 2µs typ, signal to noise+distortion (SINAD) is 61dB min
  • Total harmonic distortion (THD) is –75dB max, specified for VDD of 2.7V to 5.5V
  • Low power consumption, pin-selectable addressing via AS
  • Channel-to-channel isolation is –90dB typ at (FIN = 108Hz)
  • Sequencer operation, automatic cycle mode
  • I²C®-compatible serial interface supports standard, fast and high speed modes
  • Resolution is 10bits, out-of-range indicator/alert function
  • Shutdown mode is 1µA max
  • Linearity error is ±0.5LSB max
  • Operating temperature is –40°C to +85°C, packaging style is TSSOP
