Using a patented multi-step A/D conversion technique, the 8-bit ADC08161 CMOS A/D converter offers 500 ns conversion time, internal sample-and-hold (S/H), a 2.5V bandgap reference, and dissipates only 100 mW of power. The ADC08161 performs an 8-bit conversion with a 2-bit voltage estimator that generates the 2 MSBs and two low-resolution (3-bit) flashes that generate the 6 LBSs.

Input signals are tracked and held by the input sampling circuitry, eliminating the need for an external sample-and-hold. The ADC08161 can perform accurate conversions of full-scale input signals at frequencies from DC to typically more than 300 kHz (full power bandwidth) without the need of an external sample-and-hold (S/H).

For ease of interface to microprocessors, this part has been designed to appear as a memory location or I/O port without the need for external interfacing logic.
