Product details
Overview
ADA4092-4ARUZ from Analog Devices is a quad micropower rail-to-rail input/output operational amplifier optimized for single-supply operation from +3 V to +30 V (or ±1.5 V to ±15 V), delivering 1.4 MHz gain bandwidth, 0.4 V/µs slew rate, and 200 µA per amplifier supply current. It enables precision signal conditioning in battery-powered instrumentation, power supply control loops, and remote sensor interfaces where wide input voltage range and overvoltage protection are critical.
For engineers reviewing the ADA4092-4ARUZ datasheet, ADA4092-4ARUZ pinout, ADA4092-4ARUZ application, or ADA4092-4ARUZ equivalent, key selection considerations include its 14-lead TSSOP package, −40°C to +125°C operating temperature range, rail-to-rail I/O swing, input overvoltage protection up to ±25 V at ±5 V supplies, and guaranteed performance across full industrial temperature range.
Technical Context
The ADA4092-4ARUZ employs a dual-input-stage architecture-switching between PNP and NPN differential pairs-to maintain linear operation across the full rail-to-rail input common-mode range without phase reversal. Its output stage uses complementary bipolar transistors with collector-connected outputs to achieve true rail-to-rail swing, limited only by ~50 mV saturation voltage.
Input overvoltage protection combines 5 kΩ series resistors with bidirectional DIACs rated for ±42 V relative to supply rails, enabling safe operation with inputs exceeding rails by up to 25 V (at ±5 V) or 12 V (at ±15 V). Channel separation exceeds 100 dB at 1 kHz, supporting multichannel precision sensing without crosstalk degradation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADA4091-4ARUZ | Lower supply current (125 µA/amplifier), reduced GBW (1 MHz), no OVP circuitry. | Not suitable for field-connected sensors exposed to transients; better for ultra-low-power sleep-mode circuits. | Select ADA4091-4ARUZ only when OVP is unnecessary and supply current must be minimized below 150 µA. |
| AD8684ARUZ | Higher supply current (1.2 mA/amplifier), wider GBW (10 MHz), lower offset (125 µV), no OVP. | Designed for high-speed precision, not micropower; unsuitable for battery life-critical designs. | Choose AD8684ARUZ when bandwidth >5 MHz or offset <200 µV is required, and power budget permits >1 mA per amplifier. |
Compared with ADA4091-4ARUZ and AD8684ARUZ, the ADA4092-4ARUZ uniquely balances micropower operation (200 µA), robust input protection (±25 V OVP), and 1.4 MHz bandwidth-making it the only option among the three qualified for harsh-environment, battery-operated sensor nodes requiring both precision and fault tolerance.

FAQ
What is the maximum input overvoltage rating for ADA4092-4ARUZ at ±5 V supply?
The ADA4092-4ARUZ supports input overvoltage protection up to ±25 V relative to the supply rails when operated at ±5 V. This means inputs can safely reach +30 V or −30 V without damage or phase reversal, enabled by internal 5 kΩ resistors and ±42 V DIACs. The specification is explicitly confirmed in the General Description and Input Overvoltage Protection section of the Rev. B datasheet.
Does ADA4092-4ARUZ support true rail-to-rail input and output operation?
Yes, the ADA4092-4ARUZ provides true rail-to-rail input and output swing. Its unique dual-input-stage architecture (PNP/NPN switching) guarantees linear operation from V– to V+, and the collector-connected output transistors deliver output voltages within 50 mV of either rail across all supply conditions. This is verified in Tables 2–4 (VOH/VOL) and Figure 14–16 (dropout vs. load).
What is the operating temperature range specified for ADA4092-4ARUZ?
The ADA4092-4ARUZ is fully specified over the extended industrial temperature range of −40°C to +125°C. All key parameters-including offset voltage, supply current, CMRR, and gain bandwidth-are guaranteed across this range, as documented in the Absolute Maximum Ratings table and Electrical Specifications sections of the Rev. B datasheet.
Can ADA4092-4ARUZ be used with single-supply configurations?
Yes, the ADA4092-4ARUZ is explicitly designed for single-supply operation from +3 V to +30 V. Its rail-to-rail input and output stages, combined with input overvoltage protection, make it ideal for 3.3 V or 5 V microcontroller-based systems. The General Description states it is "guaranteed to operate from a +3 V to +30 V single supply" and demonstrates performance in Tables 2–4 at ±1.5 V, ±5 V, and ±15 V equivalents.
What package type is used for ADA4092-4ARUZ?
The ADA4092-4ARUZ is supplied in a 14-lead Thin Shrink Small Outline Package (TSSOP), designated RU-14 per the Ordering Guide. Its dimensions are 5.0 mm × 4.4 mm × 1.2 mm max, with 0.65 mm lead pitch and JEDEC MO-153-AB-1 compliance, as shown in Figure 52 of the Rev. B datasheet.
