Texas Instruments ADS7863 Analog-to-Digital Converters

Texas Instruments ADS7863 Analog-to-Digital Converters (ADCs) have two independent 12-bit ADCs in one package allowing for throughput and simultaneous sampling. The Texas Instruments ADS7863 dual, 12-bit, 2MSPS ADC has four fully differential or six pseudo-differential input channels grouped into two pairs for high-speed, simultaneous signal acquisition. This architecture provides excellent common-mode rejection of 72dB at 100kHz, which is a critical performance characteristic in noisy environments. The evaluation module is available.

Features

  • Four fully- or six pseudo-differential inputs
  • SNR: 71dB, THD: -81dB
  • Programmable and buffered internal 2.5V reference
  • Flexible power-down features
  • 2.7V to 5.5V variable power-supply ranges 
  • 45mW at 5V low-power operation 
  • -40°C to +125°C operating temperature range
  • Pin-compatible with ADS7861 and ADS8361 (SSOP package)

Applications

  • Motor control
  • Multi-axis positioning systems
  • Three-phase power control
