Analog Devices Inc. AD7982BCPZ-RL7
- Part Number:
- AD7982BCPZ-RL7
- Manufacturer:
- Analog Devices Inc.
- Ventron No:
- 3012459-AD7982BCPZ-RL7
- Description:
- IC ADC 18BIT 1MSPS PULSR 10LFCSP
- Datasheet:
- AD7982BCPZ-RL7
Description
The AD7982 is an 18-bit, successive approximation, analog-to-digital converter (ADC) that operates from a single power supply, VDD. It contains a low power, high speed, 18-bit sampling ADC and a versatile serial interface port. On the CNV rising edge, the AD7982 samples the voltage difference between the IN and IN- pins. The voltages on these pins usually swing in opposite phases between 0 V and VREF. The reference voltage, REF, is applied externally and can be set independent of the supply voltage, VDD. Its power scales linearly with throughput.
The SPI-compatible serial interface also features the ability, using the SDI input, to daisy-chain several ADCs on a single 3-wire bus and provides an optional busy indicator. It is compatible with 1.8 V, 2.5 V, 3 V, and 5 V logic, using the separate VIO supply.
The AD7982 is available in a 10-lead MSOP or a 10-lead QFN (LFCSP) with operation specified from -40°C to 85°C.
