***ow.cn: 8-Channel Octal ADC Delta-Sigma 32ksps 24-bit Serial 64-Pin LFCSP EP Tray

***ark: ADC, SIGMA-DELTA, 8-CH, 24BIT, LFCSP-64; Resolution (Bits):24bit; Sampling Rate:32kSPS; Supply Voltage Type:Single; Supply Voltage Min:2.2V; Supply Voltage Max:3.6V; ADC / DAC Case Style:LFCSP; No. of Pins:64Pins; Input Channel RoHS Compliant: Yes

***log Devices: The AD7770 is an 8-channel, simultaneous sampling ADC. Eight full sigma-delta (Σ-Δ) ADCs are on chip. The AD7770 provides a low 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 AD7770 accepts a VREF voltage from 1 V up to 3.6 V. The analog inputs accept unipolar (0 V to VREF) or true bipolar (±VREF/2) analog input signals with 3.3 V or ±1.65 V analog supply voltages, respectively for PGAGAIN = 1. The analog inputs can be configured to accept true differential, pseudo differential, or single-ended signals to match different sensor output configurations. Each channel contains a PGA, an ADC modulator and a sinc3, low latency digital filter. An SRC is provided to allow fine resolution control over the AD7770 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 AD7770 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 AD7770 to the processor. The SPI writes to and reads from the AD7770 configuration registers and for the control and reading of data from the SAR ADC. The SPI can also be configured to output the Σ-Δ conversion data. The AD7770 includes a 12-bit SAR ADC. This ADC can be used for AD7770 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 input/output pins (GPIOs), and signal conditioning, the SAR ADC can validate the Σ-Δ ADC measurements in applications where functional safety is required. In addition, the AD7770 SAR ADC includes an internal multiplexer to sense internal nodes. The AD7770 contains a 2.5 V reference and reference buffer. The reference has a typical temperature coefficient of 10 ppm/°C. The AD7770 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.

Analog to Digital Converters ADI SLP

AD7770 24-Bit Simultaneous Sampling ADC: Analog Devices AD7770 24-Bit ADCs feature eight simultaneous sampling channels designed to measure the output from voltage and current sensors in three-phase power applications. Each of AD7770's 8 channels achieves an 112dB dynamic range at 8kSPS. This allows the AD7770 ADCs to consolidate protection and measurement functions on a single ADC channel. Each channel incorporates a programmable gain amplifier (PGA) to scale various sensor outputs. The AD7770 24-Bit ADC also includes an integrated sample rate converter to simplify the process of making power quality equipment compliant with the IEC61000-4-30 Class A standard. In addition, the AD7770 ADCs eliminate the need for external components such as signal conditioning amplifiers and phase-locked loops (PLLs). The AD7770 also includes sample rate converters to enable fine adjustments of the sampling rate and 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
