HMCAD1041-40

Analog To Digital Converters (ADC) Overview

The HMCAD1041-40 is a single-channel, 10-bit analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It supports maximum sampling rates of 20 MSPS and 40 MSPS with a differential input bandwidth of 500 MHz. The device operates on a 1.8 V core supply voltage and a 1.7 V to 3.6 V I/O supply voltage. Key electrical specifications include an SNR of 61.6 dB at an 8 MHz input frequency and a total power dissipation of 15 mW at 20 MSPS or 25 mW at 40 MSPS. It features internal reference circuitry, digital error correction for missing code-free operation, and a parallel CMOS output interface. The component is housed in a 6 mm x 6 mm 40-pin QFN package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the current lifecycle status of the HMCAD1041-40 before design finalization, as legacy components may face discontinuation risks. Confirm that the specific pinout and electrical parameters match the target system requirements. Ensure compliance with RoHS directives and check for any recent product change notices that might affect long-term availability or manufacturing sourcing.

Analog To Digital Converters (ADC) Selection Notes

Select this ADC when low power dissipation and high linearity are critical constraints. The device requires careful attention to clock jitter management to maintain specified SNR performance. Designers must account for the 12-cycle pipeline delay and configure the data format (offset binary or two's complement) via the DFrMt pin according to downstream processing needs.

Analog To Digital Converters (ADC) Part Context

The HMCAD1041-40 belongs to the HMCAD1041 series of high-performance ultra-low power ADCs. It is pin-compatible with the HMCAD1041-80, HMCAD1051-40, and HMCAD1051-80 variants, allowing for flexible migration between different sampling rate options within the same package footprint without redesigning the PCB layout.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives include the HMCAD1041-80, HMCAD1051-40, and HMCAD1051-80. These parts share the same physical footprint but offer different maximum sampling rates. Verify that the alternative part's timing and power specifications align with the existing system design constraints.
