title: Analog Devices AD777X family 8-Channel, 24-Bit, Simultaneous Sampling ADCs

maintainers:
  - Ramona Nechita <ramona.nechita@analog.com>

description: |
  The AD777X family consist of 8-channel, simultaneous sampling analog-to-
  digital converter (ADC). Eight full Σ-Δ ADCs are on-chip. The
  AD7771 provides an ultralow input current to allow direct sensor
  connection. Each input channel has a programmable gain stage
  allowing gains of 1, 2, 4, and 8 to map lower amplitude sensor
  outputs into the full-scale ADC input range, maximizing the
  dynamic range of the signal chain.
