ADS7863ARGET
TEXAS INSTRUMENTS ADS7863ARGET 模数转换器, 12 bit, 2 MSPS, 单, 2.7 V, 5.5 V, VQFN
The ADS7863A is a dual, 12-bit, 2-MSPS, analog-to-digital converter ADC with four fully-differential or six pseudo-differential input channels grouped into two pairs for high-speed, simultaneous signal acquisition. Inputs to the sample-and-hold S/H amplifiers are fully differential and are maintained differential to the ADC input. This architecture provides excellent common-mode rejection of 72 dB at 100 kHz, which is a critical performance characteristic in noisy environments.
The device is pin-compatible with the ADS7861, but offers additional features such as a programmable reference output, flexible supply voltage 2.7 V to 5.5 V for AVDD and BVDD, a pseudo-differential input multiplexer with three channels per ADC, and several power-down features.
The device is offered in an SSOP-24 and a 4-mm × 4-mm QFN-24 package. The device is specified over the extended operating temperature range of –40°C to +125°C.
