MAX126CCAX+D is listed in the ADCs/DACs - Special Purpose range at ChipApex. The manufacturer field lists Analog Devices Inc./Maxim Integrated. Its product description is IC DAS 14BIT 250K 36SSOP. Review the specifications below when checking this part for your BOM.
The MAX126CCAX+D is a high-speed, multichannel, 14-bit data-acquisition system (DAS) featuring four simultaneous-sampling track/hold amplifiers. It integrates a successive-approximation ADC with a 3µs conversion time per channel and an internal +2.5V reference. The device supports ±2.5V input ranges and includes fault protection up to ±17V. It utilizes a bidirectional parallel interface compatible with DSPs and microprocessors, allowing programmable sequencing of one to four channels per CONVST pulse.
Verify the specific suffix '+D' against official Analog Devices documentation to confirm package type and temperature range specifications. Ensure compatibility with existing board layouts for the 36-pin SSOP package. Confirm that the commercial temperature range (0°C to +70°C) meets system requirements.
Select the MAX126 variant when the application requires a ±2.5V input range; use the MAX125 for ±5V inputs. Consider the internal reference for simplified designs or an external precision reference for improved accuracy over wide temperature ranges. Ensure the host processor can support the required parallel interface timing without wait states.
The MAX126CCAX belongs to the MAX125/MAX126 family of 2x4-channel, simultaneous-sampling 14-bit DAS devices. These components are designed for applications requiring precise phase information preservation across multiple channels. The CCAX designation indicates the commercial temperature range and SSOP packaging.
