Product details
Overview
TLV9162IDDFR from Texas Instruments is a dual-channel, rail-to-rail input/output operational amplifier optimized for precision signal conditioning in industrial and test equipment. It delivers ±210 µV max input offset voltage, 11 MHz gain-bandwidth product, 33 V/µs slew rate, 110 dB CMRR, and operates from 2.7 V to 16 V supply. It enables high-accuracy current sensing and low-noise microphone preamplification.
For engineers reviewing the TLV9162IDDFR datasheet, TLV9162IDDFR pinout, TLV9162IDDFR application, or TLV9162IDDFR equivalent, key selection criteria include its dual-channel SOT-23-8 package, ±0.25 µV/°C offset drift, 4.2 nV/√Hz broadband noise, MUX-friendly input stage, and robust EMIRR performance up to 1 GHz.
Technical Context
The TLV9162IDDFR employs a precision bipolar-input architecture with rail-to-rail input common-mode range extending to both supply rails and output swing within 6 mV of rails at no load. Its differential input stage supports open-loop comparator operation and multiplexer-tolerant switching without phase reversal.
It features unity-gain stability with 64° phase margin into 20 pF loads, 73 mA short-circuit output current per channel, and operates across –40°C to +125°C. The device maintains <±1.2 mV offset over temperature and exhibits <0.00005% THD+N at 1 kHz under 16 V supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.7 V to 16 V (±1.35 V to ±8 V): supports single-supply sensor interfaces and dual-supply instrumentation |
| Gain-Bandwidth Product | 11 MHz: enables stable closed-loop operation up to ~10× gain with >1 MHz signal bandwidth |
| Slew Rate | 33 V/µs: supports fast settling of 10 V step in ≤0.7 µs to 0.1% accuracy |
| Input Offset Voltage | ±0.21 mV (max): ensures <210 µV error in precision DC amplification paths |
| CMRR | 110 dB (typ): rejects >99.999% of common-mode interference in noisy industrial environments |

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 |
|---|---|---|---|
| OPA2182IDR | Lower offset (±4 µV), higher cost, 5.7 MHz GBW, 20 V supply max | Better DC accuracy but lower bandwidth limits high-speed data acquisition use | Select when ultra-low offset dominates over speed and cost sensitivity |
| AD8605ARZ-REEL7 | Higher noise (12 nV/√Hz), 10 MHz GBW, 5 V max supply, SOIC-8 only | Limited to low-voltage systems; insufficient for 12–16 V industrial sensors | Select only for legacy 5 V designs where footprint compatibility outweighs noise and supply constraints |
Compared with OPA2182IDR and AD8605ARZ-REEL7, TLV9162IDDFR uniquely balances 11 MHz bandwidth, 16 V supply capability, and 4.2 nV/√Hz noise in a compact SOT-23-8 package-making it optimal for next-generation industrial signal chains requiring both precision and speed.

FAQ
What is the maximum supply voltage for TLV9162IDDFR?
The absolute maximum supply voltage for TLV9162IDDFR is 20 V (V+ – V–), but the recommended operating range is 2.7 V to 16 V. Operating beyond 16 V risks exceeding internal junction temperature limits and degrading long-term reliability, especially at elevated ambient temperatures. Always observe derating curves in the thermal section of the SBOSA68D datasheet.
Does TLV9162IDDFR support true rail-to-rail input common-mode range?
Yes, TLV9162IDDFR supports rail-to-rail input common-mode voltage from V– to V+, including both supply rails. This is confirmed in Section 5.7 (VCM specification) and Figure 5-5–5-10 of the SBOSA68D datasheet. The input stage uses complementary PMOS/NMOS pairs to maintain functionality across the full supply range without phase reversal.
Can TLV9162IDDFR be used as a comparator?
Yes, TLV9162IDDFR can operate open-loop as a comparator due to its MUX-friendly inputs and ability to handle differential inputs up to the supply rails. However, it lacks built-in hysteresis or dedicated comparator output stages, so external hysteresis is required for noise immunity. Response time is not characterized for comparator use-designers should verify propagation delay empirically.
What is the thermal resistance (RθJA) of TLV9162IDDFR in its DDF package?
The junction-to-ambient thermal resistance (RθJA) for TLV9162IDDFR in the 8-pin SOT-23 (DDF) package is 149.6 °C/W, as specified in Section 5.5 of the SBOSA68D datasheet. This value assumes standard JEDEC 2-layer board conditions; actual performance improves with copper pour and thermal vias connected to the exposed pad (if applicable) and V–.
Is TLV9162IDDFR qualified for automotive applications?
No, TLV9162IDDFR is not AEC-Q200 qualified. It is rated for industrial temperature range (–40°C to +125°C) and intended for factory automation, test equipment, and professional audio-not automotive safety-critical systems. For automotive-grade alternatives, consult TI's TLV9062-Q1 or OPA2991-Q1 families.
