MAX1241
Key Features
- 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
