ADC08061/ADC08062
500 ns A/D Converter with S/H Function and Input
Multiplexer
General Description
Key Specifications
NOTE: These products are obsolete. This data sheet is
provided for reference only.
Using a patented multi-step A/D conversion technique, the 8bit ADC08061 and ADC08062 CMOS ADCs offer 500 ns (typ)
conversion time, internal sample-and-hold (S/H), and dissipate only 125 mW of power. The ADC08062 has a twochannel multiplexer. The ADC08061/2 performs 8-bit conversions using a multistep flash approach.
Input track-and-hold circuitry eliminates the need for an external sample-and-hold. The ADC08061/2 performs accurate
conversions of full-scale input signals that have a frequency
range of DC to 300 kHz (full-power bandwidth) without need
of an external S/H.
The digital interface has been designed to ease connection
to microprocessors and allows the parts to be I/O or memory
mapped.
