Texas Instruments ADS7881IPFBT
- Part Number:
- ADS7881IPFBT
- Manufacturer:
- Texas Instruments
- Ventron No:
- 3009542-ADS7881IPFBT
- Description:
- 2.7V-5.25V Digital, 5V Analog, 12 Bit, 4MSPS, Parallel ADC with Ref
- Datasheet:
- ads7881
Description
The ADS7881 is a 12-bit, 4-MSPS analog-to-digital converter (ADC) with an internal 2.5-V reference. It features a capacitor-based SAR architecture with inherent sample and hold. The device offers a 12-bit parallel interface with an additional byte mode for easy interfacing with 8-bit processors. It has a pseudo-differential input stage with a -IN swing of 200 mV to compensate for ground voltage mismatch and cancel common-mode noise. The ADS7881 includes an internal reference buffer and is available in 48-pin TQFP and QFN packages.
Features
12-bit resolution, 4 MHz sample rate
Zero latency
Unipolar, pseudo-differential input range: -0 V to 2.5 V
High-speed parallel interface
71 dB SNR and -88.5 dB THD at 1 MHz input
Power dissipation: 95 mW at 4 MSPS
Nap mode (10 mW power dissipation)
Power down (10 μW)
Internal reference
Internal reference buffer
Applications
Optical networking (DWDM, MEMS-based switching)
Spectrum analyzers
High-speed data acquisition systems
High-speed close-loop systems
Telecommunication
Ultra-sound detection
