Texas Instruments TLV9162IDR

Overview

TLV9162IDR from Texas Instruments is a dual-channel, rail-to-rail input/output operational amplifier optimized for precision analog signal conditioning in industrial and test equipment. It delivers ±210 µV offset voltage, 11 MHz gain-bandwidth product, 33 V/µs slew rate, 6.8 nV/√Hz input voltage noise at 1 kHz, and operates from 2.7 V to 16 V supply. It is used in high-side/low-side current sensing and multiplexed data-acquisition systems.

For engineers reviewing the TLV9162IDR datasheet, TLV9162IDR pinout, TLV9162IDR application, or TLV9162IDR equivalent, key selection criteria include DC precision (offset drift ±0.25 µV/°C), MUX-friendly input stage enabling comparator-mode operation, robust EMIRR performance, and SOIC-8 packaging suitable for space-constrained industrial PCB layouts.

Technical Context

The TLV9162IDR integrates a PMOS/NMOS complementary input stage supporting rail-to-rail common-mode input range (V– to V+), enabling direct interfacing with sensors and ADC drivers without level-shifting. Its unity-gain stable architecture supports fast settling (0.22 µs to 0.1% for 2 V step) and maintains 64° phase margin with 20 pF capacitive load.

Each channel features independent high-impedance inputs (6 TΩ common-mode, 100 MΩ differential), low quiescent current (2.4 mA per amplifier), and ±73 mA short-circuit output capability-making it suitable for driving moderate loads while preserving accuracy across –40°C to +125°C.

Key Specifications

FAQ

What is the maximum supply voltage rating for TLV9162IDR?

The absolute maximum supply voltage (V+ to V–) for TLV9162IDR is 20 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. The device is fully specified across its 2.7–16 V range for all key parameters including offset, noise, and bandwidth.

Does TLV9162IDR support true rail-to-rail output swing under load?

Yes, TLV9162IDR achieves rail-to-rail output swing: within 6 mV of either rail at no load and within 25–60 mV at 10 kΩ load (16 V supply). Output headroom scales with supply voltage-e.g., only 5 mV at 2.7 V supply with 10 kΩ load-enabling full-scale utilization of low-voltage ADC references without external level-shifting circuitry.

Can TLV9162IDR be used as a comparator without external hysteresis?

Yes, TLV9162IDR's MUX-friendly inputs allow reliable open-loop comparator operation: inputs tolerate differential voltages up to the supply rails, and propagation delay is typically <120 ns for overload recovery. However, for stable digital output without oscillation, external hysteresis (e.g., 1–10 mV) is recommended when used in noisy environments or with slow-moving input signals.

What is the thermal resistance (RθJA) of TLV9162IDR in SOIC-8 package?

The junction-to-ambient thermal resistance (RθJA) for TLV9162IDR in the SOIC-8 (D) package is 131.0°C/W, measured per JEDEC JESD51-2 standard on a 2S2P test board. This value assumes standard 2-layer PCB layout with 1-in² copper pour; actual thermal performance improves with enhanced copper area or thermal vias beneath the package body.

Is TLV9162IDR pin-compatible with other dual op amps in SOIC-8?

No-TLV9162IDR uses a non-standard SOIC-8 pinout: OUT1, IN1–, IN1+, V–, IN2+, IN2–, OUT2, V+. It is not pin-compatible with industry-standard dual op amps like LM358 or TL072, which place V+ and V– on pins 8 and 4. Layout redesign is required when substituting TLV9162IDR into existing footprints.
