Description

General part information

MAX1241 Series

The MAX1240/MAX1241 low-power, 12-bit analog-to-digital converters (ADCs) are available in 8-pin packages. The MAX1240 operates with a single +2.7V to +3.6V supply, and the MAX1241 operates with a single +2.7V to +5.25V supply. Both devices 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 37mW (VDD= 3V) at the 73ksps maximum sampling speed. A 2µA shutdown mode reduces power at slower throughput rates.The MAX1240 has an internal 2.5V reference, while the MAX1241 requires an external reference. The MAX1241 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 MAX1240/MAX1241 are available in 8-pin PDIP and SO packages.ApplicationsBattery-Powered ApplicationsInstrumentationIsolated Data AcquisitionPortable Data LoggingProcess Control
