***log Devices: The AD7779 is an 8-channel, simultaneous sampling ADC. There are eight full Σ-Δ ADCs on chip. The AD7779 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. The AD7779 accepts VREF from 1 V up to 3.6 V. The analog inputs accept unipolar (0 V to VREF/GAIN) or true bipolar (±VREF/GAIN/2 V) analog input signals with 3.3 V or ±1.65 V analog supply voltages. The analog inputs can be configured to accept true differential, pseudo differential, or singleended signals to match different sensor output configurations. Each channel contains an ADC modulator and a sinc3, low latency digital filter. An SRC is provided to allow fine resolution control over the AD7779 ODR. This control can be used in applications where the ODR resolution is required to maintain coherency with 0.01 Hz changes in the line frequency. The SRC is programmable through the serial port interface (SPI). The AD7779 implements two different interfaces: a data output interface and SPI control interface. The ADC data output interface is dedicated to transmitting the ADC conversion results from the AD7779 to the processor. The SPI interface is used to write to and read from the AD7779 configuration registers and for the control and reading of data from the SAR ADC. The SPI interface can also be configured to output the Σ-Δ conversion data. The AD7779 includes a 12-bit SAR ADC. This ADC can be used for AD7779 diagnostics without having to decommission one of the Σ-Δ ADC channels dedicated to system measurement functions. With the use of an external multiplexer, which can be controlled through the three general-purpose inputs/outputs pins (GPIOs), and signal conditioning, the SAR ADC can be used to validate the Σ-Δ ADC measurements in applications where functional safety is required. In addition, the AD7779 SAR ADC includes an internal multiplexer to sense internal nodes. The AD7779 contains a 2.5 V reference and reference buffer. The reference has a typical temperature coefficient of 10 ppm/°C. The AD7779 offers two modes of operation: high resolution mode and low power mode. High resolution mode provides a higher dynamic range while consuming 10.75 mW per channel; low power mode consumes just 3.37 mW per channel at a reduced dynamic range specification. The specified operating temperature range is −40°C to +105°C, although the device is operational up to +125°C.

AD7779 24-Bit Simultaneous Sampling ADCs: Analog Devices AD7779 includes 8-channel 24-bit simultaneous sampling ADCs designed to ensure that circuit breaker equipment powers up quickly in smart grid systems. The devices feature eight full sigma-delta (Σ-Δ) ADCs on the chip. The eight simultaneous sampling channels measure the output from current and voltage sensors in three-phase power applications. Each input channel includes a programmable gain stage enabling 1, 2, 4, and 8 gains to map lower amplitude sensor outputs in the full-scale ADC input range. This design maximizes the dynamic range of the signal chain. The AD7779 ADCs achieve an 112dB dynamic range at 8kSPS and enable the consolidation of protection and measurement functions on a single ADC channel. In addition, the AD7779 ADCs integrate a programmable gain amplifier (PGA) to scale various sensor outputs. A sample rate converter (SRC) offers a sampling rate of resolution up to 15.25µSPS. The SRC helps maintain coherency to a 0.01Hz change in line frequency over a 50Hz (-15%) to 60Hz (+15%) range. An additional low-resolution SAR ADC channel operates from a separate power supply and provides data for system and chip diagnostics.Learn More
