AD7910AKSZ-REEL7

Overview

The AD7910AKSZ-REEL7 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. It utilizes a flexible serial interface compatible with SPI, QSPI, MICROWIRE, and DSP standards. Power consumption is specified at 15 mW maximum under operational conditions with a 5 V supply. The component is housed in a compact 6-lead SC70 package.

Feature Summary

• Integrated track-and-hold amplifier for wide bandwidth signal acquisition
• Flexible power management with low standby current consumption
• Standard successive approximation architecture without pipeline delays
• Internal reference derived directly from the power supply rail

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. Ensure compatibility with required operating temperature ranges and supply voltages before integration. Confirm pinout alignment with the 6-lead SC70 footprint during schematic capture.

Selection Notes

Select this component when a single-channel, high-speed conversion is required within a minimal physical footprint. Consider the internal reference derivation if external precision references are not feasible. Evaluate power constraints against the specified normal mode and power-down current levels.

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. Both share identical pinouts and functional characteristics regarding speed and power management.

Replacement Considerations

The AD7920 serves as a higher-resolution alternative within the same package and family. Verify that the increased bit depth meets system requirements without exceeding available clock speeds or power budgets.
