AD7684BRMZ

AD7684 is a 16bit, charge redistribution, successive approximation, PulSAR® analogue-to-digital converter (ADC) that operates from a single power supply, VDD, between 2.7V to 5.5V. It contains a low power, high speed, 16bit sampling ADC with no missing codes, an internal conversion clock, and a serial, SPI-compatible interface port. The part also contains a low noise, wide bandwidth, short aperture delay, track-and-hold circuit. On the CS falling edge, it samples the voltage difference between +IN and -IN pins. The reference voltage, REF, is applied externally and can be set up to the supply voltage. Its power scales linearly with throughput. Typical application includes battery-powered equipment, data acquisition, instrumentation, medical instruments and process control.

• Throughput: 100KSPS and signal-to-noise ratio of 91dB at fIN = 1KHz

• True differential analogue input range: ±VREF 0V to VREF with VREF up to VDD on both inputs
• Single-supply operation: 2.7V to 5.5V
• Serial interface SPI®-/QSPI-™/MICROWIRE-™/DSP-compatible
• Power dissipation: 4mW at 5V, 1.5mW at 2.7V and 150μW at 2.7V/10KSPS
• Standby current: 1nA
• 8 lead MSOP package
