GENERAL DESCRIPTION
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 single-
ended, fully differential, or pseudo differential analog inputs.
Data acquisition and conversion are controlled by standard control
inputs that 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.
The AD7934-6 uses advanced design techniques to achieve very
low power dissipation at high throughput rates. The part also

features flexible power management options. An on-chip control
register allows the user to set up different operating conditions,
including analog input range and configuration, output coding,
power management, and channel sequencing.
