- Ventron No:
- 3012881-AD7887AR
- Description:
- IC ADC 12BIT 2CH SRL 8-SOIC
- ECAD Model:
-
- Datasheet:
- AD7887AR
Description
The AD7887 is a high-speed, low-power, 12-bit analog-to-digital converter (ADC) that operates from a single 2.7 V to 5.25 V power supply. It offers a throughput rate of 125 KSPS and features a single-ended sampling scheme. The AD7887 can be configured for either dual- or single-channel operation via the on-chip control register. In single-channel mode, it operates as a read-only ADC with one analog input (AINO) and an internal 2.5 V reference. In dual-channel mode, it provides a second analog input channel (AINI) and uses the Voo pin as the reference voltage.
Features
Specified for Voo of 2.7 V to 5.25 V
Flexible power/throughput rate management
Shutdown mode: 1 μA max
One or two single-ended inputs
Serial interface: SPI/QSPI/MICROWIRE/DSP compatible
8-lead narrow SOIC and MSOP packages
Applications
Battery-powered systems (personal digital assistants, medical instruments, mobile communications)
Instrumentation and control systems
High-speed modems
