Add To BomAD7779ACPZ General Description
The AD7779 is an 8-channel, simultaneous sampling ADC.There are eight full Σ-Δ ADCs on chip. The AD7779 providesan ultralow input current to allow direct sensor connection. Eachinput channel has a programmable gain stage allowing gains of1, 2, 4, and 8 to map lower amplitude sensor outputs into thefull-scale ADC input range, maximizing the dynamic range ofthe signal chain. The AD7779 accepts VREF from 1 V up to 3.6 V.The analog inputs accept unipolar (0 V to VREF/GAIN) or truebipolar (±VREF/GAIN/2 V) analog input signals with 3.3 V or±1.65 V analog supply voltages. The analog inputs can beconfigured to accept true differential, pseudo differential, or singleendedsignals to match different sensor output configurations.
Features
- 8-channel, 24-bit simultaneous sampling analog-to-digital converter (ADC)
- Single-ended or true differential inputs
- Programmable gain amplifier (PGA) per channel (gains of 1, 2, 4, and 8)
- Low dc input current
- ±1.5 nA (differential)
- ±4 nA (single-ended)
- Up to 16 kSPS output data rate (ODR) per channel
- Programmable ODRs and bandwidth
- Sample rate converter (SRC) for coherent sampling
- Sampling rate resolution up to 15.2 µSPS
- Low latency sinc3 filter path
- Adjustable phase synchronization
- Internal 2.5 V reference
- Two power modes optimizing power dissipation and performance: high resolution mode and low power mode
- Low resolution successive approximation (SAR) ADC for system and chip diagnostics
Application
- Circuit breakers
- General-purpose data acquisition
- Electroencephalography (EEG)
- Industrial process control
