AD7989-1BRMZ

AD7989-1 is a 18bit, successive approximation, analog -to-digital converter (ADC) that operate from a single power supply. It contain a low power, high speed, 18bit sampling ADC and a versatile serial interface port. On the CNV rising edge, the AD7989-1 sample the voltage difference between the IN+ and IN- pins. The voltages on these pins typically swing in opposite phases between 0V and VREF. The reference voltage, VREF, is applied externally and can be set independent of the supply voltage, VDD. Its power scales linearly with throughput. Typical application includes automated test equipment, data acquisition systems, medical instruments and machine automation.

• Performance: true differential analog input range: ±VREF, 0V to VREF with VREF between 2.4 to 5.1V
• Throughput: 100KSPS, zero latency architecture and 18bit resolution with no missing codes
