AD7910AKSZ-REEL

Overview

The AD7910AKSZ-REEL is a 10-bit successive approximation analog-to-digital converter (ADC) manufactured by Analog Devices. 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 with a wide input bandwidth exceeding 13 MHz. Power consumption is typically 3.6 mW at 250 kSPS with a 3 V supply, dropping to 1 μA maximum in standby mode. It utilizes a flexible serial interface compatible with SPI, QSPI, MICROWIRE, and DSP standards. The component is housed in a compact 6-lead SC70 package.

Feature Summary

• Integrated track-and-hold amplifier supporting high-speed data acquisition
• Flexible power management with low standby current consumption
• Internal reference derived directly from the power supply rail
• Standard successive approximation architecture without pipeline delays

Applications

• Battery-powered systems
• Medical instruments
• Data acquisition systems
• Instrumentation and control systems

Procurement Notes

Verify that the specific ordering suffix matches the required reel packaging configuration for automated assembly processes. Confirm the grade designation aligns with the necessary linearity specifications for the target application environment. Ensure compatibility with the intended operating temperature range before finalizing procurement orders.

Selection Notes

Select this component when a small footprint and low power consumption are critical design constraints. The absence of an external reference requirement simplifies the circuit layout. Verify that the single-ended input configuration meets the signal source requirements of the system design.

Part Context

This part belongs to the AD7910/AD7920 family of high-speed, low-power ADCs. While the AD7920 offers 12-bit resolution, the AD7910 provides 10-bit resolution within the same physical package and pinout configuration. Both variants share identical electrical characteristics regarding speed, power, and interface protocols.

Replacement Considerations

The AD7920 serves as a higher-resolution alternative within the same package. Other SAR ADCs may require external references or different pin configurations.
