Overview
The MAX1242ACSA+T is a low-power, 10-bit analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This component operates with a single supply voltage ranging from +2.7V to +5.25V and is packaged in an 8-pin SOIC. It features a successive-approximation ADC with a conversion time of 7.5µs and a fast track/hold time of 1.5µs. The device also includes an on-chip clock and a high-speed, 3-wire serial interface. The MAX1242ACSA+T is notable for its low power consumption, with a maximum power usage of 3mW at 73ksps sampling speed and a shutdown mode that reduces power to 2µA at slower throughput rates.
