CMOS, 10-Bit A/D Converter with Track and Hold
AVHAI 2t I] MW
CMOS 10-Bit A/D Converter
General Description
The MAX177 is a complete CMOS sampling 10-bit
analog-to-digital converter (ADC) that combines an
on-chip track-and-hold and voltage reference along
with high conversion speed and low power consump-
tion. A conversion time of 8.33ps includes settling time
for the track-and-hold. An internal buried zener refer-
ence provides low drift with low noise.
The MAX177 accepts -2.5V to +2.5V inputs. External
components are limited to only decoupling capacitors
forthe power supply and reference voltages. On-chip
clock circuitry can either be driven from an external
clock source or a crystal.
The MAX177 employs a standard microprocessor inter-
face. Three-state data outputs can be configured tor
8- or 12-bit data buses. Data access and bus release
timing specs are compatible with most popular micro-
processors without resorting to wait states.
