ML6401
8-Bit 20MSa/s A/D Converter
GENERAL DESCRIPTION
The ML6401 is a single-chip 8-bit 20 MSa/s BiCMOS
Video A/D Converter IC, incorporating a differential input
track and hold, clock generation circuitry, and reference
voltage.
The input track and hold consists of a low (4pF)
capacitance input and a fast settling operational amplifier.
The A/D conversion is accomplished through a pipeline
approach, reducing the number of required comparators
and latches. The non-over-lapping clocks required for this
architecture are all internally generated. Clock generation
circuitry requires only one 50% duty cycle clock input.
The use of error correction throughout the A/D converter
improves DNL. All bias voltages and currents required by
the A/D converter are internally generated. The digital
outputs are three-stateable.
