Overview
The MAX1243BMJA is a low-power, 10-bit analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device is part of the MAX1242/MAX1243 series and is available in an 8-pin CERDIP package. It operates with a single supply voltage ranging from +2.7V to +5.25V, making it versatile for various applications. The MAX1243BMJA features a successive-approximation ADC with a fast track/hold time of 1.5µs and an on-chip clock, along with a high-speed, 3-wire serial interface. This ADC is designed for low power consumption, with a maximum power dissipation of 3mW at 3V supply voltage and a shutdown mode that reduces power to 2µA at slower throughput rates.
