AD7910AKSZ-500RL7

Overview

The AD7910AKSZ-500RL7 is a 10-bit successive approximation analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It operates from a single supply voltage ranging from 2.35 V to 5.25 V and supports throughput rates up to 250 kSPS. The device features an internal track-and-hold amplifier capable of handling input frequencies exceeding 13 MHz. Power consumption is typically 3.6 mW at 250 kSPS with a 3 V supply. The ADC utilizes a flexible serial interface compatible with SPI, QSPI, MICROWIRE, and DSP standards. It is housed in a compact 6-lead SC70 package.

Feature Summary

• Low power dissipation with dedicated power-down mode for energy efficiency
• Internal reference derived directly from the power supply voltage
• No pipeline delays associated with the conversion process
• Flexible management of power consumption relative to serial clock speed

Applications

• Battery-powered systems
• Medical instruments
• Data acquisition systems
• Mobile communications equipment

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging details. Confirm that the component meets required environmental specifications for the intended operating temperature range. Ensure compatibility with existing system interfaces before integration.

Selection Notes

Select this component when a low pin count solution is required for space-constrained designs. Consider the 10-bit resolution and 250 kSPS throughput rate for applications requiring moderate speed and accuracy. Evaluate the single-supply operation capability against available system power rails.

Part Context

This part belongs to the AD7910/AD7920 family of high-speed, low-power ADCs. The AD7910 variant specifically provides 10-bit resolution, whereas the AD7920 offers 12-bit resolution within the same package options. Both share identical electrical characteristics regarding speed and power management.

Replacement Considerations

The AD7920 serves as a higher-resolution alternative within the same family. Verify pinout compatibility if substituting between different package types such as SC70 and MSOP.
