Product details
Overview
TLV9162SIRUGR from Texas Instruments is a dual-channel, rail-to-rail input/output precision operational amplifier with ±210 µV offset voltage, 11 MHz gain-bandwidth product, and 33 V/µs slew rate. It operates from 2.7 V to 16 V single supply (±1.35 V to ±8 V), features shutdown control per channel, and is optimized for high-side/low-side current sensing and multiplexed data acquisition in industrial automation systems.
For engineers reviewing the TLV9162SIRUGR datasheet, TLV9162SIRUGR pinout, TLV9162SIRUGR application, or TLV9162SIRUGR equivalent, key selection factors include its 10-pin X2QFN package, dual independent shutdown pins (SHDN1/SHDN2), VCM = V– specification, ±10 pA bias current, and robust EMIRR performance up to 1 GHz.
Technical Context
The TLV9162SIRUGR implements a complementary input stage enabling rail-to-rail common-mode input range (V– to V+), supports open-loop comparator operation due to MUX-friendly inputs, and maintains 110 dB CMRR at 16 V supply. Its dual independent shutdown architecture allows selective channel disablement without affecting the other amplifier's output state.
It delivers 33 V/µs slew rate with 0.70 µs 0.1% settling time (10 V step), sustains ±73 mA short-circuit output current, and achieves 4.2 nV/√Hz broadband voltage noise at 10 kHz-enabling high-fidelity signal conditioning in wideband sensor interfaces.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2182IDGKT | Lower offset (±4 µV), higher cost, SOIC-8 package (larger footprint), no shutdown | Requires external enable circuitry; better for metrology-grade DC accuracy, worse for power-gated DAQ | Choose when ultra-low offset dominates over power control and board area |
| AD8602ARMZ | Wider supply (2.7–36 V), lower GBW (10 MHz), no shutdown, MSOP-8 package | Lacks per-channel shutdown; suitable for always-on analog front-ends but not for duty-cycled sensor nodes | Choose when extended supply range and proven field reliability outweigh need for shutdown and 11 MHz bandwidth |
Compared with OPA2182IDGKT and AD8602ARMZ, TLV9162SIRUGR uniquely combines dual independent shutdown, 10-pin X2QFN miniaturization, and VCM = V– optimization-making it the only option supporting low-power, space-constrained, high-common-mode industrial current sensing without design compromises.

FAQ
What is the maximum supply voltage for TLV9162SIRUGR?
The TLV9162SIRUGR supports an absolute maximum supply voltage of 20 V (V+ to V–), with recommended operation from 2.7 V to 16 V. Exceeding 16 V continuously risks reliability degradation, though brief transients up to 20 V are tolerated per absolute maximum ratings. Always reference TI's SBOSA68D datasheet for derating curves at elevated temperatures.
Does TLV9162SIRUGR support rail-to-rail input when VCM = V–?
Yes, TLV9162SIRUGR explicitly supports rail-to-rail input with common-mode voltage down to V–, as confirmed in Section 5.7 of the datasheet under "INPUT VOLTAGE RANGE" and reinforced by the "VCM = V–" note in the ordering row. This enables direct interfacing with ground-referenced shunts and sensors without level-shifting circuitry.
How does the shutdown functionality work on TLV9162SIRUGR?
TLV9162SIRUGR provides two independent shutdown pins (SHDN1 and SHDN2). Each is active-high: applying ≥(V–)+1.1 V disables the corresponding amplifier (reducing quiescent current to 36 µA), while ≤(V–)+0.2 V enables it. Amplifier outputs enter high-impedance state during shutdown, preventing loading of downstream circuits.
What is the thermal pad connection requirement for TLV9162SIRUGR?
The exposed thermal pad on the TLV9162SIRUGR's RUG package must be soldered to the V– plane on the PCB. This connection serves both thermal dissipation and electrical reference functions-TI's datasheet Figure 4-6 and Section 6.3.10 mandate this to ensure specified thermal resistance (RθJB = 62.0 °C/W) and prevent instability or increased offset drift.
Can TLV9162SIRUGR be used as a comparator?
Yes, TLV9162SIRUGR is explicitly designed for open-loop comparator use, as stated in its "MUX-friendly/comparator inputs" feature. Its input stage operates linearly up to the supply rails, and it tolerates differential inputs beyond rails when current-limited to ≤10 mA. However, propagation delay and recovery time are not characterized-use only where speed requirements are modest (<100 ns).
