Package: WQFN-16 (3-mm ×3-mm) and TSSOP-16 Type

Manufacturer: Texas Instruments

Pinouts:

 

Description

The ADS8354, ADS7854, and ADS7254 belong to a family of pin-compatible, dual, high-speed, simultaneous-sampling, analog-to-digital converters(ADCs) that support fully-differential analog inputs.

Each device includes two individually programmable reference sources that can be used for system-level gain calibration. Also, a flexible serial interface that can operate over a wide power-supply range enables easy communication with a large variety of host controllers.

Power consumption for a given throughput can be optimized by using the two low-power modes supported by the device. All devices are fully specified over the extended industrial temperature range (–40°C to 125°C) and are available in pin-compatible, WQFN-16 (3-mm ×3-mm) and TSSOP-16 packages.

Part Number: AD7951

Function: 14-Bit, 1 MSPS, Unipolar/Bipolar Programmable Input PulSAR ADC

Package: 48-lead LQFP and LFCSP (7 mm × 7 mm) Type

Manufacturer: Analog Devices

Pinouts:

 

Description

The AD7951 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 AD7951 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 analog input on IN+ with respect to a ground sense, IN−. The AD7951 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 : 2.5 V, 10 V, ±5 V, ±10 V
2. Pins or serial SPI® compatible input ranges/mode selection
3. 14-bit resolution with no missing codes
4. INL: ±0.3 LSB typ, ±1 LSB max (±61 ppm of FSR) SNR: 85 dB @ 2 kHz
5. iCMOS® process technology
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 control
2. Medical instruments
3. High speed data acquisition
4. Digital signal processing
5. Instrumentation
6. Spectrum analysis
7. ATE
