Product details
Overview
AD8532ARUZ-REEL from Analog Devices is a dual rail-to-rail input/output operational amplifier optimized for high-output-current, single-supply applications. It delivers ±250 mA output drive, operates from 2.7 V to 6 V, features 5 V/μs slew rate and 3 MHz gain bandwidth, and is used in LCD driver stages and headphone amplification circuits where robust capacitive load driving and rail-to-rail swing are required.
For engineers reviewing the AD8532ARUZ-REEL datasheet, AD8532ARUZ-REEL pinout, AD8532ARUZ-REEL application, or AD8532ARUZ-REEL equivalent, key selection criteria include guaranteed ±250 mA output current at 5 V supply, −40°C to +85°C extended industrial temperature range, TSSOP-8 package compatibility, and absence of phase reversal under overdrive conditions.
Technical Context
The AD8532ARUZ-REEL employs a CMOS input stage with complementary N-channel and P-channel differential pairs, enabling true rail-to-rail input operation across 0 V to VS. Its folded-cascode second gain stage drives a complementary common-source output stage capable of sourcing/sinking up to ±250 mA while maintaining stability with ≥10 nF capacitive loads.
It exhibits no phase reversal when inputs exceed common-mode limits, but lacks internal short-circuit protection-direct output-to-rail shorts cause permanent damage. Input bias currents remain ultra-low (5–50 pA typ), supporting precision integrator and photodiode amplifier use cases without significant error contribution.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 6 V - supports direct interface with 3.3 V and 5 V logic/system rails without level shifting. |
| Output Current | ±250 mA - enables direct driving of low-impedance loads such as LCD segment lines or 16 Ω headphones. |
| Slew Rate | 5 V/μs at VS = 5 V - ensures faithful reproduction of audio signals up to ~800 kHz full-power bandwidth. |
| Gain Bandwidth Product | 3 MHz - provides stable unity-gain operation and sufficient loop gain for closed-loop gains up to 10× at 300 kHz. |
| Input Offset Voltage | 25 mV max (25°C), 30 mV max (−40°C to +85°C) - sets baseline DC accuracy for buffer and gain-stage applications. |
| Rail-to-Rail I/O | Input: 0 V to VS; Output: within 60–125 mV of rails at 10 mA - preserves dynamic range in single-supply signal chains. |
| Quiescent Current | 750 μA per amplifier (typ at 5 V) - allows battery-powered designs to sustain >1000-hour operation on small Li-ion cells. |
Pinout & Package
AD8532ARUZ-REEL is housed in an 8-lead TSSOP (RU suffix) surface-mount package with exposed pad for thermal enhancement. Pin 1 is marked by a dot or beveled corner; pin numbering follows standard counter-clockwise convention starting from pin 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: −IN A | Inverting input of Amplifier A | Accepts feedback network connection; referenced to common-mode voltage range 0 V to VS. |
| 2: +IN A | Non-inverting input of Amplifier A | Direct connection point for sensor, DAC, or reference signal; supports rail-to-rail common-mode swing. |
| 3: −IN B | Inverting input of Amplifier B | Independent input node for second channel; electrically isolated from Amplifier A except via shared supplies. |
| 4: +IN B | Non-inverting input of Amplifier B | Enables dual-channel configurations such as stereo headphone drive or differential line transmission. |
| 5: V− | Negative supply / ground terminal | Must be connected to system ground in single-supply operation; serves as return path for both amplifiers. |
| 6: OUT B | Output of Amplifier B | Delivers ±250 mA into resistive or capacitive loads; requires local decoupling (0.1 μF ceramic) near pin. |
| 7: OUT A | Output of Amplifier A | Identical drive capability to OUT B; layout symmetry recommended to minimize crosstalk in dual-channel PCB routing. |
| 8: V+ | Positive supply terminal | Accepts 2.7–6 V DC; must be bypassed with ≥1 μF low-ESR capacitor to suppress supply-induced distortion. |
Key Features
| Feature | Design Value |
|---|---|
| No phase reversal | Guaranteed operation without output polarity inversion when inputs exceed common-mode range - eliminates signal corruption in transient-heavy systems. |
| Rail-to-rail input and output | Full 0 V to VS input range and output swing within 60–125 mV of rails - maximizes usable voltage headroom in 3.3 V or 5 V systems. |
| High output current drive | ±250 mA per amplifier - replaces discrete transistor buffers in LCD column drivers and audio output stages. |
| Low input bias current | 5–50 pA typical - enables high-impedance sensor interfacing and precision integrator designs without significant offset drift. |
| Stable with capacitive loads | Drives ≥10 nF directly; snubber networks extend stability to 47 nF - suitable for flat-panel display timing and touch-screen driver ICs. |
Applications
| LCD Panel Driver | Headphone Amplifier |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2462IDR | Lower output current (±80 mA), slower slew rate (1.6 V/μs), wider supply range (2.7–6 V). | Not suitable for direct LCD segment drive or low-Z headphone loads; better for general-purpose buffering. | Select TLV2462IDR only when output current demand is <100 mA and cost is primary constraint. |
| OPA2350UA | Higher slew rate (38 V/μs), lower noise (7 nV/√Hz), but limited output current (±50 mA) and narrower supply (2.7–5.5 V). | Preferred for high-fidelity audio preamp stages, not for power-driving roles like LCD or speaker output. | Choose OPA2350UA when signal integrity and bandwidth outweigh drive strength requirements. |
Compared with TLV2462IDR and OPA2350UA, AD8532ARUZ-REEL uniquely balances high output current, rail-to-rail operation, and industrial temperature rating in a compact TSSOP-8 package-making it the only option among the three qualified for direct capacitive-load driving in display and audio power stages.

FAQ
What is the maximum safe output current for AD8532ARUZ-REEL in continuous operation?
The AD8532ARUZ-REEL is rated for ±250 mA output current, but continuous operation at this level depends on thermal limits. In its TSSOP-8 package (θJA = 240°C/W), sustained 250 mA output into a 5 V supply risks exceeding 150°C junction temperature unless ambient is ≤40°C and board copper area is enhanced. Derate to ±150 mA for reliable 85°C ambient operation without heatsinking.
Does AD8532ARUZ-REEL require external compensation for driving 10 nF capacitive loads?
No, AD8532ARUZ-REEL is unity-gain stable and can drive up to 10 nF capacitive loads directly without external compensation. Figures 25–28 in the Rev. F datasheet confirm stable step response with ≤10% overshoot at 10 nF. For loads >10 nF (e.g., 47 nF), a snubber network (5 Ω + 1 μF) is recommended to suppress ringing.
Can AD8532ARUZ-REEL operate from a 3.3 V supply while maintaining full rail-to-rail output swing?
Yes, AD8532ARUZ-REEL operates from 2.7 V to 6 V and maintains rail-to-rail input and output functionality at 3.3 V. At 10 mA load, output voltage swing is within 100 mV of each rail (VOH ≥ 3.2 V, VOL ≤ 0.1 V), preserving >94% of full-scale dynamic range for 3.3 V systems.
Is AD8532ARUZ-REEL pin-compatible with other dual op-amps in TSSOP-8 packages?
No, AD8532ARUZ-REEL has a nonstandard pinout: pins 1–4 are inputs (−IN A, +IN A, −IN B, +IN B), pin 5 is V−, pins 6–7 are outputs (OUT B, OUT A), and pin 8 is V+. This differs from industry-standard dual op-amp pinouts (e.g., SOIC-8 or TSSOP-8 variants of LM358, TLV2462), requiring PCB redesign for substitution.
What failure mode occurs if the output of AD8532ARUZ-REEL is shorted to V+ in single-supply operation?
Direct shorting of AD8532ARUZ-REEL's output to V+ causes immediate and irreversible damage. The device lacks internal short-circuit protection; excessive current flows through the output stage's P-channel transistor, leading to thermal runaway and junction failure. Always use series current-limiting resistors (≥20 Ω) or external foldback protection in high-risk applications.
