MAX126CCAX

ADCs/DACs - Special Purpose Overview

The MAX126CCAX is a high-speed, multichannel data acquisition system (DAS) manufactured by Analog Devices Inc./Maxim Integrated. It integrates four simultaneous-sampling track/hold amplifiers with two multiplexed inputs per amplifier, supporting eight single-ended inputs total. The device features a 14-bit, 3µs successive-approximation analog-to-digital converter (ADC), an internal +2.5V reference, and a buffered reference input. Designed for ±2.5V input ranges, it includes a fault-protected input multiplexer tolerant to ±17V. The component operates on ±5V supplies and is housed in a 36-pin SSOP package.

ADCs/DACs - Special Purpose Feature Summary

• Four simultaneous-sampling track/hold amplifiers with multiplexed inputs
• 14-bit resolution with 3µs conversion time per channel
• Fault-protected input multiplexer rated for ±17V tolerance
• Internal +2.5V reference or external reference operation capability

ADCs/DACs - Special Purpose Applications

• Multi-phase motor control systems requiring real-time signal processing
• Power network synchronization applications demanding precise timing
• Power factor monitoring and optimization in electrical systems

ADCs/DACs - Special Purpose Part Context

The MAX126CCAX belongs to the MAX125/MAX126 family of high-speed DAS devices. While the MAX125 supports a ±5V input range, the MAX126 variant is specifically configured for ±2.5V inputs. Both share identical architecture regarding sampling speed, channel count, and interface compatibility with digital signal processors and microprocessors.
