- Ventron No:
- 3014825-AD7851KNZ
- Description:
- IC ADC 14BIT SRL 333KSPS 24-DIP
- ECAD Model:
-
- Datasheet:
- AD7851KNZ
Description
The AD7851 is a high-speed, 14-bit analog-to-digital converter (ADC) that operates from a single 5 V power supply. It features a pseudo-differential input with two input ranges (0 V to VDD and -VREP/2 to VREF/2 centered about VREP/2), a 333 kHz throughput rate, and a power-down mode for low power applications. The AD7851 is available in a 24-lead PDIP, SOIC, and SSOP package.
Features
Single 5 V supply
333 kHz throughput rate
±2 LSB DNL (A Grade)
±1 LSB DNL (K Grade)
A and K Grades guaranteed to 125°C/238 kHz throughput rate
Pseudo-differential input with two input ranges
System and self-calibration with autocalibration on power-up
Read/write capability of calibration data
Low power: 60 mW typ
Power-down mode: 5 µW typ power consumption
Flexible serial interface: 8051/SPI/QSPI™/µP compatible
Applications
Digital signal processing
Speech recognition and synthesis
Spectrum analysis
DSP servo control
Instrumentation and control systems
High-speed modems
