Product details
Overview
OP496HRUZ-REEL from Analog Devices is a quad micropower rail-to-rail input/output operational amplifier optimized for battery-powered instrumentation and sensor conditioning. It delivers 450 kHz gain bandwidth, 0.3 V/µs slew rate, 300 µV max input offset voltage, 60 µA supply current per amplifier, and operates from 3 V to 12 V single supply - enabling precision low-power signal acquisition in portable medical devices and industrial monitoring systems.
For engineers reviewing the OP496HRUZ-REEL datasheet, OP496HRUZ-REEL pinout, OP496HRUZ-REEL application, or OP496HRUZ-REEL equivalent, key selection criteria include guaranteed rail-to-rail swing at 3 V, 125°C industrial temperature rating, 26 nV/√Hz noise density, capacitive load stability up to 200 pF, and absence of output phase reversal under overvoltage conditions.
Technical Context
The OP496HRUZ-REEL employs a composite PNP/NPN input stage enabling true rail-to-rail common-mode input range (0 V to VS) and output swing within 70 mV of rails at ±1 mA load. Its architecture eliminates output phase reversal when inputs exceed supply rails - a critical advantage over conventional single-supply op amps requiring external clamping diodes.
Stability is maintained with capacitive loads ≤200 pF without external compensation. The device features high open-loop gain (≥300 V/mV), 65 dB CMRR over full common-mode range, and low 0.1 Hz–10 Hz noise (0.8 µV p-p), supporting precision DC-coupled sensing in RTD bridges and battery voltage monitors.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464IPWR | Higher supply current (550 µA/amplifier), lower GBW (6.4 MHz), no 125°C rating | Not suitable for extended-temperature industrial use; better for higher-speed but less power-constrained designs | Select only if >1 MHz bandwidth required and 125°C operation unnecessary |
| LMV324IDR | Lower precision (7 mV VOS max), no rail-to-rail input, 100 µA supply current | Acceptable for cost-sensitive consumer electronics where offset and input range are noncritical | Choose only for non-precision applications with relaxed accuracy and temperature requirements |
Compared with TLV2464IPWR and LMV324IDR, OP496HRUZ-REEL uniquely combines micropower operation (60 µA), rail-to-rail I/O, 125°C qualification, and sub-millivolt offset - making it irreplaceable in battery-powered industrial sensors requiring long-term stability.

FAQ
What is the maximum capacitive load the OP496HRUZ-REEL can drive without oscillation?
The OP496HRUZ-REEL is unconditionally stable driving capacitive loads up to 200 pF in unity-gain configuration, as verified in the datasheet's "Driving Capacitive Loads" section and TPC 32 transient response plots. For loads exceeding 200 pF, in-the-loop compensation (e.g., series resistor + feedback capacitor) is required to maintain phase margin above 45°. This capability eliminates external isolation resistors in many sensor interface layouts.
Does the OP496HRUZ-REEL support true rail-to-rail input at 3 V supply?
Yes, the OP496HRUZ-REEL guarantees rail-to-rail input common-mode range from 0 V to VS across its full operating temperature range (–40°C to +125°C) at 3 V supply, as confirmed in the "INPUT CHARACTERISTICS" table (VCM = 0 V to 3.0 V, 0°C ≤ TA ≤ 125°C). This allows direct interfacing with grounded sensors and 3 V reference voltages without level-shifting circuitry.
What is the typical supply current per amplifier for OP496HRUZ-REEL at 25°C and 5 V supply?
The typical supply current per amplifier for OP496HRUZ-REEL is 60 µA at 25°C and 5 V supply, with a guaranteed maximum of 80 µA over the full –40°C to +125°C temperature range. This value is measured with VOUT = 2.5 V and RL = ∞, as specified in the "POWER SUPPLY" section of the datasheet - enabling predictable power budgeting for quad-channel designs.
Can OP496HRUZ-REEL be used in circuits where input voltages exceed the supply rails?
Yes, the OP496HRUZ-REEL tolerates input voltages up to 15 V (absolute maximum rating), but input current must be limited to ≤5 mA to prevent damage, as detailed in the "Input Overvoltage Protection" section. Its novel PNP/NPN input stage prevents output phase reversal during such overvoltage events - unlike many single-supply op amps that require external clamping diodes.
Is the OP496HRUZ-REEL pin-compatible with other members of the OP196 family?
No, OP496HRUZ-REEL is not pin-compatible with OP196 or OP296 due to differing channel counts and pinouts: OP196 is 8-lead SOIC, OP296 is 8-lead SOIC/TSSOP, while OP496HRUZ-REEL is 14-lead TSSOP with unique pin mapping (e.g., V+ on pin 4, V– on pin 11). Board redesign is required when migrating from single/dual to quad variants.
