Analog Devices Inc. ADA4830-2BCPZ-R7

Overview

ADA4830-2BCPZ-R7 from Analog Devices is a dual high-speed difference amplifier with integrated short-to-battery (up to 18 V) input protection, −3 dB bandwidth of 84 MHz at 5 V supply, 250 V/µs slew rate, and fixed 0.50 V/V gain optimized for CVBS video signal reception in automotive rearview camera systems.

For engineers reviewing the ADA4830-2BCPZ-R7 datasheet, ADA4830-2BCPZ-R7 pinout, ADA4830-2BCPZ-R7 application, or ADA4830-2BCPZ-R7 equivalent, this page delivers verified specifications, validated dual-channel pin mapping, automotive-grade temperature range (−40°C to +125°C), and confirmed alternatives for video receiver design in harsh environments.

Technical Context

The ADA4830-2BCPZ-R7 implements a precision resistive difference amplifier topology with four matched on-chip resistors, enabling fixed 0.50 V/V differential-to-single-ended conversion. Its core uses a 0.35 µm CMOS rail-to-rail op amp stage with extended input common-mode range (−10 V to +9.5 V on 5 V supply).

Short-to-battery protection operates independently of enable state and supply presence, using fast-switching clamping circuitry to hold internal nodes safe during 18 V overvoltage events. The STB flag pin provides open-drain logic-level fault indication with 10.3 V typical trigger threshold under 5 V operation.

Key Specifications

Pinout & Package

ADA4830-2BCPZ-R7 is housed in a 16-lead 3 mm × 3 mm LFCSP package with exposed thermal pad (EPAD) requiring PCB soldering for thermal management. Pin 1 is top-left corner (VOUT1), pin 16 is bottom-right (VREF1). All power and ground pins are duplicated per channel for layout flexibility.

FAQ

What is the maximum input voltage the ADA4830-2BCPZ-R7 can withstand without damage?

The ADA4830-2BCPZ-R7 supports protected input voltage range of −9 V to +20 V per the datasheet Absolute Maximum Ratings table. It reliably withstands continuous 18 V short-to-battery conditions on either INP or INN pin while maintaining functionality and output integrity-no external clamping diodes required. This rating applies across the full −40°C to +125°C operating temperature range.

Does the ADA4830-2BCPZ-R7 require external components for basic CVBS video reception?

No, the ADA4830-2BCPZ-R7 operates as a complete video receiver with minimal external components: only 0.1 µF bypass capacitors on each +VS pin and pull-up resistors on STB1/STB2 pins for fault monitoring. Its integrated 0.50 V/V gain, internal VREF biasing, and short-to-battery protection eliminate the need for series AC-coupling capacitors, external gain-setting resistors, or discrete protection devices in standard CVBS applications.

How does the STB pin function on the ADA4830-2BCPZ-R7?

The STB1 and STB2 pins on the ADA4830-2BCPZ-R7 are open-drain logic outputs that assert low (≤253 mV) when input voltage exceeds 10.3 V (typical) on the corresponding INP/INN pair-indicating a short-to-battery fault. During normal operation (<9.8 V), STB remains high-impedance and requires an external pull-up resistor to +VS. This enables microcontroller GPIO monitoring without loading the video path.

Can the ADA4830-2BCPZ-R7 operate from a 3.3 V supply?

Yes, the ADA4830-2BCPZ-R7 operates across 2.9 V to 5.5 V supply range. At 3.3 V, it delivers 73 MHz −3 dB bandwidth (0.1 V_p-p, 1 kΩ), 165 V/µs slew rate, and maintains 0.49–0.51 V/V gain accuracy. Input common-mode range shrinks to −8 V to +6 V, and STB trigger threshold lowers to 7.8 V typical-fully documented in Table 2 of the Rev. C datasheet.

Is the ADA4830-2BCPZ-R7 pin-compatible with the automotive-grade ADA4830-2WBCPZ-R7?

Yes, the ADA4830-2BCPZ-R7 and ADA4830-2WBCPZ-R7 share identical 16-lead 3 mm × 3 mm LFCSP package, pinout, and electrical interface. The W-grade variant adds AEC-Q100 qualification and tighter parametric limits over temperature but requires no PCB layout changes or schematic modifications when substituted in existing designs.
