Product details
Overview
TLV9162IDGKR 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 requiring low drift and robust EMIRR performance.
For engineers reviewing the TLV9162IDGKR datasheet, TLV9162IDGKR pinout, TLV9162IDGKR application, or TLV9162IDGKR equivalent, key selection criteria include its dual-channel SOIC-8 package, ±0.25 µV/°C offset drift, 110 dB CMRR, MUX-friendly inputs enabling comparator-mode operation, and guaranteed operation from –40°C to +125°C.
Technical Context
The TLV9162IDGKR employs a precision bipolar-input architecture with PMOS/NMOS input stage overlap to enable true rail-to-rail common-mode input range (V– to V+), supporting differential inputs up to supply rails. Its unity-gain stable design integrates internal compensation for predictable 11 MHz bandwidth across load conditions.
It features robust electromagnetic interference rejection (EMIRR > 100 dB at 100 MHz), high short-circuit output current (±73 mA), and low quiescent current (2.4 mA per amplifier), making it suitable for noise-sensitive, wide-supply industrial front-ends where DC accuracy and dynamic response must coexist.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 16 V (±1.35 V to ±8 V): supports single- or dual-supply operation in battery-powered and industrial 12 V/15 V systems. |
| Gain-Bandwidth Product | 11 MHz: enables stable closed-loop operation up to ~10 MHz at G = +1, suitable for fast-settling sensor amplification and active filtering. |
| Input Offset Voltage | ±0.21 mV (max @ 25°C): ensures sub-1 LSB error in 12-bit systems with 2.5 V reference and 1× gain. |
| Offset Drift | ±0.25 µV/°C: contributes < ±0.3 mV total drift over –40°C to +125°C, critical for uncalibrated temperature-stable measurements. |
| Slew Rate | 33 V/µs: supports full-scale 10 V step response in < 0.3 µs, essential for driving ADC drivers and fast comparators. |
| Input Voltage Noise | 6.8 nV/√Hz @ 1 kHz: minimizes contribution to system noise floor in microphone preamps and precision instrumentation. |
| CMRR | 110 dB (typ @ 16 V): rejects common-mode interference in noisy factory automation environments with long sensor cables. |
Pinout & Package
Dual-channel SOIC-8 (D package), 4.90 mm × 6.00 mm body, surface-mount, RoHS-compliant. Thermal pad not present; standard SOIC thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Output, Channel 1 | Amplified output node; rail-to-rail swing (≤60 mV from rails @ 16 V, 10 kΩ load) enables direct interfacing with SAR ADCs. |
| 2 (IN1–) | Inverting Input, Channel 1 | Differential input terminal; accepts signals from V– to V+, including open-loop comparator use without external clamping. |
| 3 (IN1+) | Noninverting Input, Channel 1 | Differential input terminal; MUX-friendly input structure allows direct connection to multiplexer outputs without level-shifting. |
| 4 (V–) | Negative Supply Rail | Reference for both channels; must be connected to ground or negative supply; thermal pad (if present) connects here in WSON variants - not applicable to DGKR. |
| 5 (IN2+) | Noninverting Input, Channel 2 | Independent input for second channel; identical electrical specs to IN1+, enabling matched dual-sensor conditioning. |
| 6 (IN2–) | Inverting Input, Channel 2 | Independent input for second channel; supports differential configurations such as current-sense amplifiers with matched gain resistors. |
| 7 (OUT2) | Output, Channel 2 | Second independent output; crosstalk < –100 dB @ 10 kHz ensures isolation in multi-channel data acquisition. |
| 8 (V+) | Positive Supply Rail | Primary power rail; supplies both amplifiers; PSRR of 110 dB suppresses supply ripple in shared-rail systems. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization with single-supply microcontrollers and ADCs; eliminates need for level-shifting circuitry. |
| MUX-friendly/comparator inputs | Supports direct connection to analog multiplexers and open-loop comparator operation without external diode clamps or pull-ups. |
| Low offset voltage drift (±0.25 µV/°C) | Reduces calibration frequency in field-deployed equipment; maintains accuracy across automotive and industrial temperature ranges. |
| High EMIRR (>100 dB @ 100 MHz) | Suppresses RF-induced errors in wireless test equipment and factory-floor environments with strong EMI sources. |
| Unity-gain stable with 11 MHz GBW | Guarantees stability without external compensation in buffer, gain-of-1, or active filter configurations. |

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), lower noise (5.7 nV/√Hz), but higher IQ (700 µA/channel); requires external compensation for unity-gain stability. | Better suited for ultra-low-drift metrology; less ideal for battery-powered DAQ due to higher quiescent current. | Select OPA2182IDR only when sub-10 µV offset and < 6 nV/√Hz noise are mandatory and supply headroom permits higher IQ. |
| AD8602ARMZ | Higher offset (±600 µV), lower bandwidth (8 MHz), no specified EMIRR; rail-to-rail I/O, same SOIC-8 package. | Cost-optimized for general-purpose industrial use; lacks MUX-friendly inputs and robust RF immunity. | Choose AD8602ARMZ for non-critical, cost-sensitive applications where 110 dB CMRR and 100+ dB EMIRR are not required. |
Compared with OPA2182IDR and AD8602ARMZ, TLV9162IDGKR provides the optimal balance of low offset drift (±0.25 µV/°C), high-speed precision (11 MHz/33 V/µs), and industrial-grade EMI resilience - all within a 2.4 mA/channel power envelope and SOIC-8 footprint.

FAQ
What is the maximum operating temperature range for TLV9162IDGKR?
The TLV9162IDGKR is specified from –40°C to +125°C ambient temperature, meeting industrial-grade reliability requirements. This range is validated across all electrical parameters in the datasheet, including offset voltage drift, CMRR, and open-loop gain, ensuring consistent performance in factory automation and motor control environments.
Does TLV9162IDGKR support single-supply operation?
Yes, TLV9162IDGKR supports true single-supply operation from 2.7 V to 16 V. Its rail-to-rail input and output stages allow common-mode input voltages from V– to V+ and output swings within 60 mV of either rail (at 16 V, 10 kΩ load), enabling direct interface with 3.3 V or 5 V microcontrollers and ADCs without level-shifting circuitry.
Can TLV9162IDGKR be used as a comparator?
Yes, TLV9162IDGKR can be used in open-loop comparator mode due to its MUX-friendly inputs - its input stage operates correctly with differential inputs up to the supply rails, and it exhibits fast overload recovery (120 ns). However, it lacks built-in hysteresis or push-pull output; external hysteresis and output conditioning are recommended for reliable digital edge detection.
What is the typical quiescent current per channel for TLV9162IDGKR?
The typical quiescent current per channel for TLV9162IDGKR is 2.4 mA at 25°C and 16 V supply, rising to 2.84 mA maximum over –40°C to +125°C. This value is measured with zero output load and applies to both channels independently, making total device IQ ≈ 4.8 mA under nominal conditions.
Is TLV9162IDGKR pin-compatible with other devices in the TLV916x family?
No, TLV9162IDGKR (SOIC-8) is not pin-compatible with TLV9161 (SOT-23-5/SC70-5) or TLV9164 (SOIC-14/TSSOP-14). Within the dual-channel variants, only TLV9162 variants sharing the D (SOIC-8) package - such as TLV9162IDR - have identical pinout. Always verify package-specific pin functions using Table 4-3 in the SBOSA68D datasheet.
