Product Descriptions
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 reference 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 busrelease 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.
