_______________General Desc ription
The MAX195 is a 16-bit successive-approximation ana-
log-to-digital converter (ADC) that combines high
speed, high accuracy, low power consumption, and a
10μA shutdown mode. Internal calibration circuitry cor-
rects linearity and offset errors to maintain the full rated
performance over the operating temperature range with-
out external adjustments. The capacitive-DAC architec-
ture provides an inherent 85ksps track/hold function.
The MAX195, with an external reference (up to +5V),
offers a unipolar (0V to V
REF
) or bipolar (-V
REF
to V
REF
)
pin-selectable input range. Separate analog and digital
supplies minimize digital-noise coupling.
The chip select (
CS
) input controls the three-state serial-
data output. The output can be read either during conver-
sion as the bits are determined, or following conversion at
up to 5Mbps using the serial clock (SCLK). The end-of-
conversion (
EOC
) output can be used to interrupt a
processor, or can be connected directly to the convert
input (
CONV
) for continuous, full-speed conversions.
The MAX195 is available in 16-pin DIP, wide SO, and
ceramic sidebraze packages.
