Description
The RHF1401 is a 14-bit analog-to-digital
converter that uses pure (ELDRS-free) CMOS
0.25 µm technology combining high performance,
radiation robustness and very low power
consumption.
Ceramic SO-48 package
The upper metallic lid is not electrically connected to any
pins, nor to the IC die inside the package.
The RHF1401 is based on a pipeline structure
and digital error correction to provide excellent
static linearity. Specifically designed to optimize
power consumption, the device only dissipates
85 mW at 20 Msps, while maintaining a high level
of performance. The device also integrates a
proprietary track-and-hold structure to ensure a
large effective resolution bandwidth.
Voltage references are integrated in the circuit to
simplify the design and minimize external
components. A tri-state capability is available on
the outputs to allow common bus sharing. A data-
ready signal, which is raised when the data is
valid on the output, can be used for
synchronization purposes.
The RHF1401 has an operating temperature
range of -55° C to +125° C and is available in a
small 48-pin ceramic SO-48 package.
