MAX1190ECM+D

Analog To Digital Converters (ADC) Overview

The MAX1190ECM+D is a dual-channel, 10-bit analog-to-digital converter (ADC) operating at a maximum sampling rate of 120Msps. It utilizes a fully differential wideband track-and-hold architecture with a 400MHz full-power bandwidth and accepts ±1Vp-p differential analog inputs. The device operates from a single 3.1V to 3.6V analog supply and features an internal 2.048V precision bandgap reference. Digital outputs are parallel, CMOS-compatible three-state signals with user-selectable two's complement or offset binary formats. Power consumption is 492mW in normal operation, reducing to 10mW in sleep mode and 3.3µW in shutdown mode.

Analog To Digital Converters (ADC) Procurement Notes

Verify the component authenticity by checking the manufacturer markings against official documentation. Confirm the package type matches the specified 48-pin TQFP-EP configuration. Ensure the temperature range meets the extended industrial requirements of -40°C to +85°C. Cross-reference the ordering suffix to confirm lead-free status and specific revision details before finalizing procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high-speed dual-channel conversion is required within a low-power constraint. The 120Msps sampling rate and 10-bit resolution suit applications demanding excellent dynamic performance. Consider the integrated reference and flexible output interface for simplified system design. Evaluate the pin-compatible lower-speed variants if the maximum clock frequency exceeds application needs.

Analog To Digital Converters (ADC) Part Context

The MAX1190 belongs to a family of high-performance, low-power ADCs designed for imaging, instrumentation, and digital communications. It offers pin-compatible versions with varying speeds, such as the MAX1180 series, and 8-bit alternatives like the MAX1195–MAX1198. This positioning allows designers to scale performance while maintaining board layout consistency across different product tiers.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives include the MAX1180 through MAX1184 for lower speed grades and the MAX1195 through MAX1198 for 8-bit resolutions. Verify that the substitute part meets the required sampling rate and dynamic performance specifications for the specific application context.
