General Description
The MAX121 is a complete, BiCMOS, serial-output,
sampling 14-bit analog-to-digital converter (ADC) that
com bines an on-chip track/hold and a low-drift, low-
noise, buried-zener voltage reference with fast conversion
speed and low power consumption. The throughput rate
is as high as 308k samples per second (ksps). The full-
scale analog input range is ±5V.
The MAX121 utilizes the successive-approximation archi-
tecture with a high-speed DAC to achieve both fast
conversion speeds and low-power operation. Operating
with +5V and -12V or -15V power supplies, power con-
sumption is only 210mW.
The MAX121 can be directly interfaced to the serial port
of most popular digital-signal processors, and comes
in space-saving 16-pin DIP and SO and smaller 20-pin
SSOP packages. The MAX121 operates with TTL- and
CMOS-compatible clocks in the frequency range from
1.1MHz to 5.5MHz. All logic inputs and outputs are TTL -
and CMOS-compatible. This data sheet includes applica-
tion notes for easy interface to TMS320, µPD77230, and
ADSP2101 digital-signal processors, as well as µPs using
the Motorola SPI and QSPI interface standards.
