ADC08161
500 ns A/D Converter with S/H Function and
2.5V Bandgap Reference
General Description
Using a patented multi-step A/D conversion technique, the
8-bit ADC08161 CMOS A/D converter offers 500 ns conver-
sion 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 cir-
cuitry, 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.
