Product Description

The AD7887ARZ is a high speed, low power 12-bit Analog-to-digital Converter (ADC) capable of 125kSPS throughput rate. The input track-and-hold acquires a signal in 500ns and features a single-ended sampling scheme. The output coding for the converter is straight binary and the part is capable of converting full power signals of up to 2.5MHz. It can be configured for either dual or single-channel operation via the on-chip control register. There is a default single-channel mode that allows the converter to be operated as a read-only ADC. In 1-channel operation, there is one analog input (AIN0) and the AIN1/VREF pin assumes its VREF function. This VREF pin allows the user access to the parts internal 2.5V reference or the VREF pin can be overdriven by an external reference to provide the reference voltage for the part. This external reference voltage has a range of 2.5V to VDD. The analog input range on AIN0 is 0 to VREF.
Flexible power/throughput rate management
One or two single-ended inputs
Serial interface - SPI®/QSPI™/MICROWIRE™/DSP compatible
