HMCAD1040-80

Analog To Digital Converters (ADC) Overview

The HMCAD1040-80 is a dual-channel, high-performance, low-power analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It features 10-bit resolution with a maximum sampling rate of 80 MSPS and an alternative mode at 65 MSPS. The device utilizes a proprietary structure with digital error correction to ensure no missing codes across the full-scale range. It incorporates internal reference circuitry and operates on a 1.8 V core supply voltage with a 1.7–3.6 V I/O supply voltage. The ADC provides parallel CMOS output data and supports differential clock inputs in LVDS, LVPeCL, sine wave, or CMOS formats. It is housed in a 9 x 9 mm, 64-pin QFN (LP9E) package.

Analog To Digital Converters (ADC) Feature Summary

• Dual-channel architecture with independent power-down capabilities for each channel.

• Portable test equipment
• Digital oscilloscopes
• IF communication receivers

Analog To Digital Converters (ADC) Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or direct channels. Confirm that the specific part number matches the required 80 MSPS variant rather than the 40 MSPS version. Ensure handling procedures account for electrostatic sensitivity as indicated in the datasheet absolute maximum ratings.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel conversion is required within a compact footprint. Compare performance metrics such as SNR and power dissipation against the HMCAD1040-40 if lower speed suffices. Verify that the system clock jitter remains below specified limits to maintain optimal signal-to-noise ratio during operation.

Analog To Digital Converters (ADC) Part Context

This device belongs to the HMCAD1040 series of high-speed ADCs from Analog Devices. It shares pin compatibility with the HMCAD1040-40, HMCAD1050-40, and HMCAD1050-80 models, facilitating design flexibility across different speed and resolution requirements within the same product family.

Analog To Digital Converters (ADC) Replacement Considerations

The HMCAD1040-40 is a pin-compatible alternative offering a lower maximum sampling rate of 40 MSPS. Designers requiring reduced power consumption or lower bandwidth may consider this substitute while maintaining the same physical layout constraints.
