Overview

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 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.
