SBAS294A – JUNE 2004 – REVISED MARCH 2006

Dual, 12-Bit, 65MSPS, +3.3V

Analog-to-Digital Converter

•

Single +3.3V Supply

The ADS5232 is a dual, high-speed, high dynamic

range, 12-bit pipelined analog-to-digital converter

•

(ADC). This converter includes a high-bandwidth

of the converter without any external reference

circuitry. The internal reference can be disabled,

multiplexing and testing on a PC board.

The

techniques to provide excellent differential linearity for

demanding imaging applications. The ADS5232 is
