ADA4830-1BCPZ-R7

Overview

The ADA4830-1BCPZ-R7 is a single-channel high-speed difference amplifier from Analog Devices, designed for automotive and harsh environments. It integrates input short-to-battery protection up to 18 V and features an enable pin. Key electrical parameters include a gain bandwidth product of 84 MHz, a slew rate of 250 V/µs, and a supply voltage range of 2.9 V to 5.5 V. The device operates with a quiescent current of 6.8 mA per channel and supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Integrates input overvoltage (short-to-battery) protection capable of withstanding up to 18 V on input pins without external series capacitors.
• Provides a dedicated short-to-battery output flag (STB) for wire diagnostics and fault indication.
• Features a wide input common-mode voltage range compatible with single 5 V supplies.
• Includes an enable/output disable mode to reduce power consumption when the device is not in use.

Applications

• Automotive vision systems
• Automotive infotainment
• Surveillance systems

Procurement Notes

Verify the specific suffix 'BCPZ' against official documentation to confirm package type and temperature grade. Ensure compatibility with the required PCB footprint for the LFCSP package. Confirm that the intended application environment falls within the specified operating temperature range. Check for any specific automotive qualification requirements if deploying in vehicle safety systems.

Selection Notes

Select this component for applications requiring robust video signal reception in noisy environments. The integrated short-to-battery protection eliminates the need for large series capacitors. Consider the fixed 0.50 V/V gain for direct interfacing with video decoders. Evaluate the space-saving LFCSP package for size-constrained designs.

Part Context

This part belongs to the ADA4830 family of monolithic high-speed difference amplifiers. The single-channel variant (ADA4830-1) complements the dual-channel ADA4830-2. Both are built on a CMOS process and share similar performance characteristics, including high slew rates and low noise, tailored for CVBS and high-speed video signals.

Replacement Considerations

The ADA4830-1W is the automotive-grade version of this component. Verify if the W suffix is required for specific automotive qualification standards. No other direct substitutes are documented in the provided source material.
