- Part Number:
- AD7989-1BRMZ-RL7
- Manufacturer:
- Analog Devices Inc.
- Ventron No:
- 3013143-AD7989-1BRMZ-RL7
- Description:
- IC ADC 18BIT 100KSPS SAR 10MSOP
- Datasheet:
- AD7989-1BRMZ-RL7
Description
The AD7989-1/AD7989-5 are 18-bit, successive approximation, analog-to-digital converters (ADCs) that operate from a single power supply, VDD. They contain a low power, high speed, 18-bit sampling ADC and a versatile serial interface port. On the CNV rising edge, the AD7989-1/AD7989-5 sample the voltage difference between the IN and IN- pins. The voltages on these pins usually swing in opposite phases between 0 V and Vier. The reference voltage, REF, is applied externally and can be set independent of the supply voltage, VDD. Its power scales linearly with throughput.
The AD7989-1/AD7989-5 are serial peripheral interface (SPI) compatible, which features the ability, using the SDI input, to daisy-chain several ADCs on a single 3-wire bus. It is compatible with 1.8 V, 2.5 V, 3 V, and 5 V logic, using the separate VIO supply.
The AD7989-1/AD7989-5 are available in a 10-lead MSOP or a 10-lead LFCSP with operation specified from -40°C to 85°C.
