ADC08062

Contents

Using a patented multi-step A/D conversion technique, the 8-bit 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 two-channel multiplexer. The ADC08061/2 family performs an 8-bit conversion using a 2-bit voltage estimator that generates the 2 MSBs and two low-resolution (3-bit) flashes that generate the 6 LSBs.

Input track-and-hold circuitry eliminates the need for an external sample-and-hold. The ADC08061/2 family 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.
