DESCRIPTION
The ADC08B200 is a high speed analog-to-digital
converter (ADC) with an integrated capture buffer.
The 8-bit, 200 MSPS A/D core is based upon the
proven ADC08200 with integrated track-and-hold and
is optimized for low power consumption. This device
contains a selectable size capture buffer of up to
1,024 bytes that allows fast capture of an input signal
with a slower readout rate. An on-chip clock PLL
circuit provides the option of on-chip clock rate
multiplication to provide the high speed sampling
clock.
The ADC08B200 is resistant to latch-up and the
outputs are short-circuit proof. The top and bottom of
the ADC08B200's reference ladder are available for
connections, enabling a wide range of input
possibilities. The digital outputs are TTL/CMOS
compatible with a separate output power supply pin
to support interfacing with 2.7V to 3.3V logic. The
digital inputs and outputs are low voltage TTL/CMOS
compatible and the output data format is straight
binary.
The ADC08B200Q runs on an Automotive Grade
Flow and is AEC-Q100 Grade 2 Qualified.
The ADC08B200 is offered in a 48-pin plastic
package (TQFP) and is specified over the extended
industrial temperature range of 40°C to +105°C. An
evaluation board is available to assist in the easy
evaluation of the ADC08B200.
