Analog Devices Inc. AD7715ACHIPS-3
- Part Number:
- AD7715ACHIPS-3
- Manufacturer:
- Analog Devices Inc.
- Ventron No:
- 3018571-AD7715ACHIPS-3
- Description:
- IC ADC 16BIT SIGMA-DELTA CHIP
- Datasheet:
- AD7715
Description
The AD7715 is a 16-bit, sigma-delta analog-to-digital converter (ADC) with a programmable gain front end. It is designed for low-frequency measurement applications and can accept input signals directly from a transducer. The AD7715 features a differential analog input and a differential reference input. It operates from a single supply (3 V or 5 V) and can handle unipolar and bipolar input signal ranges. The AD7715 has a three-wire serial interface that can be configured for SPI, QSPI, MICROWIRE™, and DSP-compatible operation.
Features
16-bit resolution, no missing codes
±0.0015% nonlinearity
Programmable gain front end (gains of 1, 2, 32, and 128)
Differential analog input capability
Three-wire serial interface (SPI-, QSPI, MICROWIRE™, and DSP-compatible)
Ability to buffer the analog input
3 V (AD7715-3) or 5 V (AD7715-5) operation
Low supply current: 450 μA maximum @ 3 V supplies
Low-pass filter with programmable output update rate
16-lead SOIC/PDIP/TSSOP package
Applications
Smart sensors
Microcontroller-based systems
DSP-based systems
Data acquisition systems
Industrial process control
Medical instrumentation
Weigh scales
Pressure transducers
Temperature sensors
