Product details
Overview
AD8592ARMZ-REEL from Analog Devices is a dual CMOS rail-to-rail input/output operational amplifier with independent shutdown control per channel, 3 MHz gain bandwidth, 5 V/μs slew rate, ±250 mA output drive, and 750 μA per amplifier supply current - designed for audio buffering and battery-powered instrumentation in single-supply systems.
For engineers reviewing the AD8592ARMZ-REEL datasheet, AD8592ARMZ-REEL pinout, AD8592ARMZ-REEL application, or AD8592ARMZ-REEL equivalent, key selection criteria include shutdown current (≤1 μA total), rail-to-rail swing capability at 2.5–6 V supply, high capacitive load drive (up to 10 nF), low input bias current (5–50 pA), and MSOP-10 package compatibility with space-constrained portable designs.
Technical Context
The AD8592ARMZ-REEL integrates two independent amplifiers in a single 10-lead MSOP package, each with dedicated shutdown inputs (SDA and SDB) enabling selective channel disablement. Its CMOS input stage delivers ultra-low input bias current (5 pA typ), supporting precision integrators and photodiode interfaces.
It employs a compound folded-cascode architecture with complementary common-source rail-to-rail output stage (M15/M16), delivering full-swing output voltage (e.g., 4.9 V at 10 mA load with 5 V supply) while maintaining unity-gain stability and immunity to phase reversal within supply rails.
Key Specifications

| Gain Bandwidth Product | 3 MHz - supports stable closed-loop operation up to ~300 kHz at gain = 10, suitable for audio and data acquisition. |
| Slew Rate | 5 V/μs - ensures <1.6 μs settling to 0.01% for 2.5 V step, critical for fast-settling sample-and-hold circuits. |
| Output Drive Current | ±250 mA - drives heavy loads including LCD reference levels, PC audio jacks, and 600 Ω line drivers without external buffers. |
| Shutdown Supply Current | ≤1 μA total (both amps) - extends battery life in portable headsets and handheld instruments during idle periods. |
| Input Bias Current | 5 pA typical - minimizes error in high-impedance sensor interfaces and integrator applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2462IDR | Lower output drive (±35 mA), higher supply current (550 μA/amp), no shutdown function. | Suitable only for low-current signal conditioning; cannot replace AD8592ARMZ-REEL in headphone or LCD reference roles. | Select TLV2462IDR only when shutdown and high drive are unnecessary and cost is primary constraint. |
| MCP6022-E/SN | Lower bandwidth (10 MHz), higher input offset (250 μV max), no rail-to-rail output (100 mV dropout), no shutdown. | Limited to mid-speed precision sensing; unsuitable for audio output or full-swing DAC buffering. | Choose MCP6022-E/SN only for DC-coupled sensor amplification where output swing margin is acceptable. |
Compared with TLV2462IDR and MCP6022-E/SN, AD8592ARMZ-REEL uniquely combines high output current, per-channel shutdown, rail-to-rail I/O, and low input bias in a single MSOP-10 package - making it irreplaceable in portable audio, capacitive-load driving, and battery-sensitive sample-and-hold designs.

FAQ
What is the maximum capacitive load the AD8592ARMZ-REEL can drive stably?
The AD8592ARMZ-REEL is specified to drive up to 10 nF capacitive loads without external compensation while maintaining stability and unity-gain bandwidth above 2 MHz. This capability eliminates the need for isolation resistors in LCD panel reference drivers and long-cable line-driving applications, unlike many general-purpose op-amps that require series resistance or snubber networks for loads >100 pF. The AD8592ARMZ-REEL achieves this through optimized internal compensation and robust output stage design.
Does the AD8592ARMZ-REEL support true rail-to-rail input and output operation?
Yes, the AD8592ARMZ-REEL supports rail-to-rail input (common-mode range from V– to V+) and rail-to-rail output (swing within 60 mV of rails at 10 mA load with 5 V supply). This is enabled by dual-input differential pairs (n-channel and p-channel) and a complementary common-source output stage. The feature allows direct interfacing with CMOS DACs, ASICs, and other wide-swing devices in single-supply systems without level-shifting circuitry - a key enabler for compact portable designs.
How does the shutdown function operate on the AD8592ARMZ-REEL?
The AD8592ARMZ-REEL features independent active-high shutdown inputs: SDA (Pin 5) controls Amplifier A, and SDB (Pin 6) controls Amplifier B. When either input is pulled low (≤0.5 V at −40°C to +85°C), its corresponding amplifier enters shutdown mode, reducing supply current to ~1.4 mA per channel and placing the output in high-impedance state. When both SDA and SDB are low, total supply current drops to ≤1 μA. This per-channel control enables flexible power management in dual-path applications like headset mic/speaker interfaces.
What is the typical input bias current of the AD8592ARMZ-REEL, and why does it matter?
The AD8592ARMZ-REEL has a typical input bias current of 5 pA at 25°C, with a maximum of 60 pA over −40°C to +85°C. This ultra-low value is critical for high-impedance applications such as photodiode transimpedance amplifiers, precision integrators, and electret microphone bias networks - where even nanoamp-level leakage would introduce significant offset or time-constant errors. The CMOS input architecture enables this performance, distinguishing AD8592ARMZ-REEL from bipolar-input op-amps with bias currents orders of magnitude higher.
Can the AD8592ARMZ-REEL be used in a single-supply differential line driver configuration?
Yes, the AD8592ARMZ-REEL can implement a single-supply differential line driver - for example, using one amplifier as an inverting stage and the other as a non-inverting stage with matched feedback networks to generate balanced ±2 V outputs from a 5 V supply into 600 Ω. Its 3 MHz bandwidth, 5 V/μs slew rate, and ±250 mA drive ensure <0.7% THD from 20 Hz to 15 kHz. Unlike transformer-based solutions, this approach occupies less board space, operates down to DC, and allows unbalanced operation (shorting one output to ground) without gain change - as demonstrated in Analog Devices' Application Note AN-632.
