MAX1243BCSA+ by Analog Devices

+2.7V to +5.25V, Low-Power, 10-Bit Serial ADCs in SO-8


The MAX1242/MAX1243 are low-power, 10-bit analog-to-digital converters (ADCs) available in 8-pin packages. They operate with a single +2.7V to +5.25V supply and feature a 7.5µs successive-approximation ADC, a fast track/hold (1.5µs), an on-chip clock, and a high-speed, 3-wire serial interface. Power consumption is only 3mW (VDD = 3V) at the 73ksps maximum sampling speed. A 2µA shutdown mode reduces power at slower throughput rates. The MAX1242 has an internal 2.5V reference, while the MAX1243 requires an external reference. The MAX1243 accepts signals from 0V to VREF, and the reference input range includes the positive supply rail. An external clock accesses data from the 3-wire interface, which connects directly to standard microcontroller I/O ports. The interface is compatible with SPI, QSPI™, and MICROWIRE®. Excellent AC characteristics and very low power combined with ease of use and small package size make these converters ideal for remote-sensor and data-acquisition applications, or for other circuits with demanding power consumption and space requirements. The MAX1242/MAX1243 are available in 8-pin PDIP and SO packages.
