MAX120 Datasheet 500ksps / 12-bit Adcs

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: 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.
