MAX120/MAX122

500ksps, 12-Bit ADCs with Track/Hold

and Reference

General Description

The MAX120/MAX122 complete, BiCMOS, sampling 12-bit

analog-to-digital converters (ADCs) combine an on-chip

track/hold (T/H) and a low-drift voltage reference with fast

conversion speeds and low-power consumption. The T/H’s

350ns acquisition time combined with the MAX120’s 1.6µs

conversion time results in throughput rates as high as 500k

samples per second (ksps). Throughput rates of 333ksps

are possible with the 2.6µs conversion time of the MAX122.

The MAX120/MAX122 accept analog input voltages from

-5V to +5V. The only external components needed are

decoupling capacitors for the power-supply and refer-

ence voltages. The MAX120 operates with clocks in the

0.1MHz to 8MHz frequency range. The MAX122 accepts

0.1MHz to 5MHz clock frequencies.

The MAX120/MAX122 employ a standard microprocessor

(µP) interface. Three-state data outputs are configured

to operate with 12-bit data buses. Data-access and bus-

release timing specifications are compatible with most

popular µPs without resorting to wait states. In addition,

the MAX120/MAX122 can interface directly to a first-in,

first-out (FIFO) buffer, virtually eliminating µP interrupt

overhead. All logic inputs and outputs are TTL/CMOS

compatible. For applications requiring a serial interface,

refer to the MAX121.
