Analog Devices Inc. AD7922ARMZ-REEL7
- Part Number:
- AD7922ARMZ-REEL7
- Manufacturer:
- Analog Devices Inc.
- Ventron No:
- 3012888-AD7922ARMZ-REEL7
- Description:
- IC ADC DUAL 12BIT 2CH 8MSOP
- Datasheet:
- AD7922ARMZ-REEL7
Description
The AD7912/AD7922 are 10-bit and 12-bit, high-speed, low-power, 2-channel successive approximation ADCs, respectively. They operate from a single 2.35 V to 5.25 V power supply and feature throughput rates of up to 1 MSPS. The parts contain a low noise, wide bandwidth track-and-hold amplifier, which can handle input frequencies in excess of 6 MHz. The conversion process and data acquisition are controlled using CS and the serial clock, allowing the devices to interface with microprocessors or DSPs. The conversion rate is determined by the SCLK signal. The input signal is sampled on the falling edge of CS and the conversion is also initiated at this point. The channel to be converted is selected through the DIN pin, and the mode of operation is controlled by CS. The serial data stream from the DOUT pin has a channel identifier bit and mode identifier bit, which provide information about the converted channel and the current mode of operation.
Features
Fast throughput rate: 1 MSPS
Specified for Voo of 2.35 V to 5.25 V
Low power:
4.8 mW typ at 1 MSPS with 3 V supplies
15.5 mW typ at 1 MSPS with 5 V supplies
Wide input bandwidth: 71 dB minimum SNR at 100 kHz input frequency
Flexible power/serial clock speed management
No pipeline delays
High speed serial interface: SPI/QSPI™/MICROWIRE/DSP compatible
Standby mode: 1 μA maximum
Daisy-chain mode
8-lead TSOT package
8-lead MSOP package
Applications
Battery-powered systems:
Personal digital assistants
Medical instruments
Mobile communications
Instrumentation and control systems
Data acquisition systems
High speed modems
Optical sensors
