General Description
The MAX191 is a monolithic, CMOS, 12-bit analog-to-
digital converter (ADC) featuring differential inputs,
track/hold (T/H), internal voltage reference, internal or
external clock, and parallel or serial P interface. The
MAX191 has a 7.5s conversion time, a 2s acquisition
time, and a guaranteed 100ksps sample rate.
The MAX191 operates from a single +5V supply or from
dual ±5V supplies, allowing ground-referenced bipolar
input signals. The device features a logic power-down
input, which reduces the 3mA VDD supply current to
50A max, including the internal-reference current.
Decoupling capacitors are the only external compo-
nents needed for the power supply and reference. This
ADC operates with either an external reference, or an
internal reference that features an adjustment input for
trimming system gain errors.
The MAX191 provides three interface modes: two 8-bit
parallel modes, and a serial interface mode that is com-
patible with SPITM, QSPITM, and MICROWIRETM serial-
interface standards.
