The AD7934-6 is a 12-bit, high speed, low power, successive approximation (SAR) analog-to-digital converter (ADC). The part operates from a single 2.7 V to 5.25 V power supply and features throughput rates up to 625 kSPS. The part contains a low noise, wide bandwidth, differential track-and-hold amplifier that handles input frequencies up to 50 MHz. The AD7934-6 features four analog input channels with a channel sequencer that allows a preprogrammed selection of channels to be converted sequentially. This part can accept either singleended, fully differential, or pseudo differential analog inputs. Data acquisition and conversion are controlled by standard control inputs, which allow for easy interfacing to microprocessors and DSPs. The input signal is sampled on the falling edge of CONVST, which is also the point where the conversion is initiated. The AD7934-6 has an accurate on-chip 2.5 V reference that can be used as the reference source for the analog-to-digital conversion. Alternatively, this pin can be overdriven to provide an external reference.
