Dual, 12-Bit, 65MSPS, +3.3V Analog-to-Digital Converter
The ADS5232 is a dual, high-speed, high dynamic range, 12-bit pipelined Analog-to-digital converter (ADC). Th 712 is converter includes a high-bandwidth sample-and-hold Amplifier that gives excellent spurious performance up to and beyond the Nyquist rate. The differential nature of the sample-and-hold Amplifier and ADC circuitry minimizes even-order harmonics and gives excellent common-mode noise immunity.
The ADS5232 provides for setting the full-scale range of the converter without any external reference circuitry. The internal reference CAN be disabled, allowing low-drive, external references to be used for improved tracking in multichannel systems.
The ADS5232 provides an over-range indicator flag to indicate an input signal that exceeds the full-scale input range of the converter. This flag CAN be used to reduce the gain of front-end gain control circuitry. There is also an output enable pin to allow for multiplexing and testing on a PC board.
The ADS5232 employs digital error correction techniques to provide excellent differential linearity for demanding imaging applications. The ADS5232 is available in a TQFP-64 package.
