ADA4896-2ACPZ-RL

Overview

The ADA4896-2ACPZ-RL is a dual, unity-gain stable, low noise, rail-to-rail output, high-speed voltage feedback amplifier. It operates on a supply voltage range of 3 V to 10 V with a quiescent current of 3 mA per amplifier. The device features a -3 dB bandwidth of 230 MHz at G = +1 and a slew rate of 120 V/μs. Input voltage noise is 1 nV/√Hz at 100 kHz and 2.4 nV/√Hz at 10 Hz. It settles to 0.1% in 45 ns and offers an open-loop gain of 110 dB. The component is housed in an 8-lead LFCSP package and operates over an extended industrial temperature range from -40°C to +125°C.

Feature Summary

• Rail-to-rail output stage designed for driving heavy feedback loads and capacitive loads.
• Low wideband noise performance with minimal 1/f noise for high-speed applications.
• High dynamic range with spurious-free dynamic range of -80 dBc at 2 MHz.
• Low power consumption with a quiescent current of 3 mA per amplifier.

Applications

• Ultrasound amplifiers
• Low noise preamplifiers
• PLL loop filters
• High performance ADC drivers
• DAC buffers

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the reel packaging configuration. Ensure the component matches the exact part number ADA4896-2ACPZ-RL for the 8-lead LFCSP package. Cross-reference the revision history to confirm the datasheet version aligns with your design requirements. Confirm RoHS compliance status through the manufacturer's certification documents before procurement.

Selection Notes

Select this amplifier for applications requiring high speed combined with low noise and low power consumption. The device is suitable for systems operating within a 3 V to 10 V supply range. Consider the 8-lead LFCSP package for surface-mount assembly. Verify that the required bandwidth and settling time meet the system specifications. The rail-to-rail output capability makes it appropriate for single-supply or split-supply designs.

Part Context

The ADA4896-2 is part of a family of low noise, high-speed voltage feedback amplifiers manufactured by Analog Devices Inc. using a proprietary SiGe bipolar process. This technology enables high performance characteristics such as low input noise and high bandwidth. The device is designed to operate over an extended industrial temperature range, making it suitable for demanding environments.

Replacement Considerations

The ADA4897-1 and ADA4897-2 are complementary devices in the same family. The ADA4897-1 is available in 8-lead SOIC and 6-lead SOT-23 packages, while the ADA4897-2 is available in a 10-lead MSOP package. These variants include a disable feature not present in the ADA4896-2. Package differences must be considered when substituting.
