Analog Devices Inc. ADA4853-3YRUZ-R7

Overview

ADA4853-3YRUZ-R7 from Analog Devices is a triple, rail-to-rail output, low-power video operational amplifier optimized for standard-definition video signal conditioning. It delivers 100 MHz −3 dB bandwidth (at 5 V), 120 V/µs slew rate, 0.20% differential gain, and 0.10° differential phase - enabling high-fidelity composite/S-video buffering in automotive infotainment and portable multimedia systems.

For engineers reviewing the ADA4853-3YRUZ-R7 datasheet, ADA4853-3YRUZ-R7 pinout, ADA4853-3YRUZ-R7 application, or ADA4853-3YRUZ-R7 equivalent, key selection criteria include its 14-lead TSSOP package, three independent disable controls (DISABLE 1/2/3), ultralow 0.1 µA disabled current, and guaranteed −40°C to +105°C operation - critical for battery-powered and automotive video front-ends.

Technical Context

The ADA4853-3YRUZ-R7 implements a voltage-feedback architecture with a high-slew-rate input stage supporting true single-supply operation down to 2.65 V. Its rail-to-rail output stage swings within 200 mV of either rail into 150 Ω, while maintaining 22 MHz 0.5 dB flatness and <45 ns 0.1% settling time - essential for SD video fidelity.

Each of the three amplifiers features independent enable/disable logic referenced to ground, with turn-on time of 120 ns and turn-off time of 1.5 µs. Input common-mode range extends from −0.2 V to V_CC − 1.2 V, allowing direct interface with baseband video sources without level-shifting.

Key Specifications

Pinout & Package

FAQ

What is the maximum supply voltage for ADA4853-3YRUZ-R7?

The absolute maximum supply voltage for ADA4853-3YRUZ-R7 is 5.5 V. The recommended operating range is 2.65 V to 5 V. Operation above 5.5 V risks permanent damage per the Absolute Maximum Ratings table. At 5 V, the device achieves full 100 MHz bandwidth and 120 V/µs slew rate - both de-rated at lower voltages. ADA4853-3YRUZ-R7 must never be operated beyond 5.5 V, even transiently.

Does ADA4853-3YRUZ-R7 support true single-supply operation with input signals below ground?

Yes, ADA4853-3YRUZ-R7 supports true single-supply operation with input common-mode voltage extending 200 mV below the negative rail (e.g., −0.2 V when −VS = 0 V). This enables direct coupling of baseband video signals without clamping diodes or level-shifters. The input stage remains linear and distortion-free across this range, as confirmed by Figure 37 (VOS vs. VCM) and General Description section. ADA4853-3YRUZ-R7 maintains specified differential gain/phase performance under these conditions.

How does the DISABLE pin functionality work on ADA4853-3YRUZ-R7?

ADA4853-3YRUZ-R7 features three independent active-low DISABLE pins (pins 1, 2, 3) - one per amplifier. Pulling any DISABLE pin ≤ 1.2 V disables its corresponding amplifier, reducing quiescent current to 0.1 µA max. Turn-on time is 120 ns; turn-off time is 1.5 µs. All DISABLE pins are referenced to ground and require no external pull-ups. When disabled, output impedance rises significantly (Figure 22), effectively isolating the channel. ADA4853-3YRUZ-R7 does not require sequencing of DISABLE pins relative to power-up.

What is the thermal performance of ADA4853-3YRUZ-R7 in its 14-lead TSSOP package?

ADA4853-3YRUZ-R7 in the 14-lead TSSOP package has a junction-to-ambient thermal resistance (θ_JA) of 120°C/W on a standard JEDEC 4-layer board. Maximum safe power dissipation decreases linearly from ~2.5 W at −40°C ambient to ~0.5 W at +85°C ambient (Figure 6). The exposed pad must be soldered to a PCB ground plane for optimal thermal performance. Junction temperature must remain below 150°C to prevent parametric shift or reliability degradation. ADA4853-3YRUZ-R7 thermal design requires attention to copper area and airflow in high-density layouts.

Can ADA4853-3YRUZ-R7 drive a 75 Ω video load directly?

Yes, ADA4853-3YRUZ-R7 is fully characterized driving 75 Ω loads. At 5 V supply, output voltage swing is specified as 0.1 V to 4.8 V (typical) into 75 Ω (Table 2), supporting full 1 V_PP video signals. Differential gain/phase (0.22%/0.10°) and 0.5 dB flatness (22 MHz) are measured with 150 Ω loads, but performance remains compliant at 75 Ω per Figure 42 and Applications Information section. ADA4853-3YRUZ-R7 short-circuit current (160 mA sink / 120 mA source) ensures robust 75 Ω drive capability without foldback.
