MAX1261 Overview
Key Specifications
Package: QSOP
Mount Type: Surface Mount
Pins: 28
Operating Voltage: 3.6 V
Description
The MAX1261/MAX1263 low-power, 12-bit analog-todigital converters (ADCs) feature a successive-approximation ADC, automatic power-down, fast wake-up (2µs), an on-chip clock, +2.5V internal reference, and a high-speed, byte-wide parallel interface. They operate with a single +3V analog supply and feature a VLOGIC pin that allows them to interface directly with a +1.8V to +5.5V digital supply.
Key Features
- Power consumption is only 5.7mW (VDD = VLOGIC) at the maximum sampling rate of 250ksps
- Powering down between conversions can cut supply current to under 10µA at reduced sampling rates
- Both devices offer software-configurable analog inputs for unipolar/bipolar and single-ended/pseudo-differential operation
- The MAX1261 is available in a 28-pin QSOP package, while the MAX1263 is available in a 24-pin QSOP
- For pin-compatible +5V, 12-bit versions, refer to the MAX1262/MAX1264 data sheet
