AD7952 datasheet

Description :

The AD7952 is a 14-bit, charge redistribution, successive approximation register (SAR) architecture analog-to-digital converter (ADC) fabricated on Analog Devices, Inc.’s iCMOS high voltage process. The device is configured through hardware or via a dedicated write-only serial configuration port for input range and operating mode. The IC contains a high speed 14-bit sampling ADC, an internal conversion clock, an internal reference (and buffer), error correction circuits, and both serial and parallel system interface ports. A falling edge on CNVST samples the fully differential analog inputs on IN+ and IN−. The device features four different analog input ranges and three different sampling modes: warp mode for the fastest throughput, normal mode for the fastest asynchronous throughput, and impulse mode where power is scaled with throughput. Operation is specified from −40°C to +85°C.

Features

1. Multiple pins/software-programmable input ranges :
+5 V (10 V p-p), +10 V (20 V p-p), ±5 V (20 V p-p), ±10 V (40 V p-p)
2. Pins or serial SPI®-compatible input ranges/mode selection
3. Throughput
1 MSPS (warp mode)
800 kSPS (normal mode)
670 kSPS (impulse mode)
4. 14-bit resolution with no missing codes
5. INL: ±0.3 LSB typical, ±1 LSB maximum (±61 ppm of FSR)
6. 5 V internal reference: typical drift 3 ppm/°C; TEMP output
7. No pipeline delay (SAR architecture)
8. Parallel (14- or 8-bit bus) and serial 5 V/3.3 V interface

Applications 

1. Process controls
2. Medical instruments
3. High speed data acquisition
4. Digital signal processing
5. Instrumentation
6. Spectrum analysis
