DESCRIPTION
The MAX1242/MAX1243 are low-power, 10-bit analogto-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. An external clock accesses data from the 3-wire interface, which connects directly to standard microcontroller I/O ports. Excellent AC characteristics and very low power combined with ease of use and small package size make these converters ideal for remote-sensor and dataacquisition applications, or for other circuits with demanding power consumption and space requirements. The MAX1242/MAX1243 are available in 8-pin DIP and SO packages. _________________...
