Product details
Overview
ADA4853-3YRUZ from Analog Devices is a triple, rail-to-rail output, ultralow-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 datasheet, ADA4853-3YRUZ pinout, ADA4853-3YRUZ application, or ADA4853-3YRUZ equivalent, key selection criteria include its 14-lead TSSOP package with three independent disable controls, 2.65–5 V single-supply operation, rail-to-rail output swing within 200 mV of either rail, and guaranteed −40°C to +105°C operation for automotive-grade reliability.
Technical Context
The ADA4853-3YRUZ integrates three independent voltage-feedback op amps sharing a common supply but featuring individual DISABLE pins (Pins 1, 2, 3), enabling per-channel power gating. Its input stage supports common-mode voltages from −0.2 V to VCC − 1.2 V, while the rail-to-rail output stage sustains 0.5 dB flatness to 22 MHz into 150 Ω - critical for SD video fidelity.
Each amplifier consumes only 1.4 mA quiescent current (typical at 5 V) and drops to 0.1 µA in disabled state. The device uses a true single-supply architecture with no internal level-shifting circuitry, preserving low-noise performance (22 nV/√Hz at 100 kHz) and fast enable time (120 ns).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| −3 dB Bandwidth | 100 MHz at G = +1, 5 V supply - supports full NTSC/PAL baseband video bandwidth without attenuation. |
| Slew Rate | 120 V/µs (typical) - ensures distortion-free reproduction of fast video transients (e.g., sync pulses). |
| Differential Gain / Phase | 0.20% / 0.10° at RL = 150 Ω - meets stringent SD video color fidelity requirements (SMPTE 253M). |
| Supply Range | 2.65 V to 5 V - enables direct interface with 3.3 V and 5 V logic/video subsystems without level shifters. |
| Quiescent Current | 1.4 mA per amplifier (typical at 5 V) - extends battery life in portable video recorders and cameras. |
| Disable Current | 0.1 µA per amplifier - reduces system standby power by >99.9% when channel is inactive. |
| Output Swing | Within 200 mV of either rail into 150 Ω - preserves dynamic range in single-supply video driver stages. |
Pinout & Package
ADA4853-3YRUZ is packaged in a 14-lead TSSOP (Thin Shrink Small Outline Package) with exposed pad thermally connected to ground. Pin 14 is the common positive supply (+VS); Pins 8 and 12 are shared negative supply (−VS). Each amplifier has dedicated input and output terminals plus individual disable control.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | DISABLE 1 / DISABLE 2 / DISABLE 3 | Active-low digital control inputs; each independently disables one amplifier to reduce quiescent current to 0.1 µA. |
| 4, 11, 13 | +IN1 / +IN2 / +IN3 | Non-inverting inputs for each amplifier; support common-mode range down to −0.2 V (below −VS). |
| 5, 10, 14 | −IN1 / −IN2 / −IN3 | Inverting inputs; configured for unity-gain buffer or gain-of-two video line driver topologies. |
| 6, 9, 15 | VOUT1 / VOUT2 / VOUT3 | Rail-to-rail output terminals; drive 75 Ω or 150 Ω video loads with <200 mV headroom at both rails. |
| 7, 8, 12 | −VS | Common negative supply pin (shared across all amplifiers); must be tied to ground in single-supply operation. |
| 14 | +VS | Positive supply input (2.65–5 V); decoupling capacitor required between Pin 14 and Pin 8/12 for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Triple independent disable control | Enables per-channel power management in multi-path video systems (e.g., camera + display + encoder), reducing total system idle power. |
| 0.5 dB flatness to 22 MHz | Preserves luminance/chrominance amplitude balance across full NTSC (4.2 MHz) and PAL (5.0–5.5 MHz) baseband spectra. |
| Rail-to-rail output with 200 mV headroom | Maximizes usable signal swing in 3.3 V systems (e.g., 0.2–3.1 V output range), avoiding clipping on sync tips and white peaks. |
| −40°C to +105°C operating range | Qualified for under-hood automotive applications including rear-view cameras and dashboard displays per AEC-Q100 stress test conditions. |
| Low 22 nV/√Hz input voltage noise | Maintains SNR > 60 dB in 5 MHz video bandwidth, preventing visible noise overlay on analog video outputs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple video op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADA4853-3WYRUZ | Automotive-qualified variant (AEC-Q100 Grade 2); identical electrical specs but validated for −40°C to +105°C with enhanced reliability testing. | Required for production automotive infotainment systems requiring formal qualification documentation and PPAP support. | Select ADA4853-3WYRUZ when automotive compliance (not just temperature range) is mandated by OEM tier-1 requirements. |
| LMH6733MA/NOPB | Triple 350 MHz op amp with higher bandwidth and slew rate, but 10× higher quiescent current (15 mA/amplifier) and no disable function. | Suitable for high-definition video or wideband instrumentation where power is secondary to speed. | Choose LMH6733MA/NOPB only if >100 MHz bandwidth is essential and battery life or thermal constraints are not limiting. |
Compared with ADA4853-3WYRUZ, the ADA4853-3YRUZ offers identical performance but lacks formal AEC-Q100 certification - making it appropriate for industrial or consumer designs where automotive qualification is unnecessary. Versus LMH6733MA/NOPB, ADA4853-3YRUZ trades bandwidth for 90% lower power and integrated disable, better matching SD video and portable system needs.

FAQ
What is the operating temperature range for ADA4853-3YRUZ?
The ADA4853-3YRUZ is rated for operation from −40°C to +105°C, matching the extended temperature requirement for automotive and industrial video applications. This range is explicitly specified in the Absolute Maximum Ratings table for the 14-lead TSSOP package and confirmed across all DC and AC performance parameters in the datasheet's "Specifications with 5 V Supply" section.
Does ADA4853-3YRUZ support true single-supply operation with input below ground?
Yes. The ADA4853-3YRUZ input common-mode voltage range extends to −0.2 V relative to the negative supply rail (−VS), enabling direct interface with video signals that include negative sync tips in single-supply configurations. This is documented in Table 1 and Table 2 under "Input Common-Mode Voltage Range" and verified in Figure 37 (VOS vs. VCM).
How does the DISABLE function work on ADA4853-3YRUZ?
ADA4853-3YRUZ features three independent active-low DISABLE pins (Pins 1, 2, 3). Pulling any DISABLE pin low (<1.2 V) reduces the corresponding amplifier's quiescent current to 0.1 µA (typical), while maintaining high isolation (>80 dB) between input and output. Turn-on time is 120 ns, and turn-off time is 1.5 µs - values measured per Table 2 and shown in Figure 47.
Can ADA4853-3YRUZ drive a 75 Ω video load?
Yes. The ADA4853-3YRUZ output stage is characterized for 75 Ω loads in the "Specifications with 5 V Supply" table, delivering 0.1 V to 4.8 V output swing (RL = 75 Ω) and maintaining 0.5 dB flatness to 22 MHz. Output current capability (160 mA sink / 120 mA source) ensures stable driving of terminated coaxial video lines without oscillation.
What is the package type and thermal performance of ADA4853-3YRUZ?
ADA4853-3YRUZ uses a 14-lead TSSOP package with an exposed thermal pad that must be soldered to a PCB ground plane. Its thermal resistance θJA is 120°C/W on a JEDEC 4-layer board (Table 4), enabling reliable operation at full load up to +105°C ambient when proper PCB copper area and via count are implemented per Analog Devices' layout guidelines.
