Analog Devices Inc. ADA4853-3YRUZ-RL

Overview

ADA4853-3YRUZ-RL from Analog Devices is a triple, rail-to-rail output, ultralow-power video operational amplifier in 14-lead TSSOP package. It delivers 100 MHz −3 dB bandwidth, 120 V/µs slew rate, and 0.20% differential gain with 0.10° differential phase-optimized for standard-definition video signal conditioning in automotive infotainment and portable multimedia systems.

For engineers reviewing the ADA4853-3YRUZ-RL datasheet, ADA4853-3YRUZ-RL pinout, ADA4853-3YRUZ-RL application, or ADA4853-3YRUZ-RL equivalent, key selection criteria include disable current (0.1 µA), rail-to-rail output swing (within 200 mV of rails), 2.65–5 V supply range, −40°C to +105°C operating temperature, and 3-channel independent disable control.

Technical Context

The ADA4853-3YRUZ-RL integrates three independent voltage-feedback op amps with dedicated DISABLE pins per channel, enabling selective power gating without affecting adjacent amplifiers. Its input stage supports common-mode voltages from −0.2 V to V_CC − 1.2 V, and its rail-to-rail output stage sustains 150 Ω load drive while maintaining 22 MHz 0.5 dB flatness.

Each amplifier operates at 1.4 mA quiescent current per channel and achieves <1.5 µA disable current. The device uses a single-supply architecture compatible with 3 V and 5 V systems, with specified performance across −40°C to +105°C-meeting requirements for automotive safety and infotainment subsystems.

Compared with ADA4853-3WYRUZ-RL, the ADA4853-3YRUZ-RL offers identical pinout and electrical behavior but excludes AEC-Q100 certification-reducing cost for non-automotive applications. Versus LMH6733MA/NOPB, it trades bandwidth and drive strength for 90% lower quiescent current and integrated channel disable, making it optimal for portable and cost-sensitive SD video systems.

FAQ

What is the maximum load capacitance the ADA4853-3YRUZ-RL can drive without instability?

The ADA4853-3YRUZ-RL maintains stability with up to 10 pF capacitive load when properly compensated using a 25 Ω series resistor (snubber) at the output. Figure 10 in the Rev. G datasheet confirms stable small-signal response up to 10 pF; beyond that, peaking occurs. For larger loads (e.g., 50 pF coaxial cable), external isolation or feedback network adjustment is required. Always verify pulse response (Figure 29) in final layout.

Does the ADA4853-3YRUZ-RL support true single-supply operation with input below ground?

Yes. The ADA4853-3YRUZ-RL supports input common-mode voltage down to −0.2 V relative to −VS (typically ground), enabling DC-coupled inputs in single-supply configurations. This allows direct connection to sensors or DACs with negative-going video sync pulses. Input overdrive recovery time is specified at 40 ns (Figure 33), confirming robust handling of transient undershoot.

How does the disable function affect crosstalk between channels in the ADA4853-3YRUZ-RL?

When disabled, each channel's output impedance rises to >1 MΩ (Figure 22), reducing inter-channel coupling. Measured crosstalk remains ≤−66 dB at 5 MHz (Table 1) regardless of disable state. However, Figure 48 shows hostile crosstalk (VOUT1→VOUT2) degrades to −50 dB at 100 MHz when all channels are active-so disabling unused channels improves high-frequency isolation in dense layouts.

Can the ADA4853-3YRUZ-RL be used in a dual-supply ±2.5 V configuration?

Yes. Though optimized for single-supply use, the ADA4853-3YRUZ-RL operates with symmetric supplies from ±2.5 V (total 5 V). The input common-mode range extends to −2.7 V to +1.3 V, and output swings to within 200 mV of either rail. Power supply rejection is −75 dB (±PSR) at low frequency (Figure 20), supporting noise-sensitive analog front-ends in instrumentation.

What is the thermal resistance (θ_JA) of the ADA4853-3YRUZ-RL in its 14-lead TSSOP package?

The ADA4853-3YRUZ-RL in 14-lead TSSOP has a junction-to-ambient thermal resistance (θ_JA) of 120°C/W on a standard JEDEC 4-layer board (Table 4). With 4.2 mA total quiescent current at 5 V, power dissipation is ~21 mW-resulting in <2.6°C junction rise above ambient. For high-temperature automotive use, ensure ≥2 cm² copper pour under the exposed pad connected to ground.
