Product details
Overview
TLV2186IDSGT from Texas Instruments is a dual-channel, zero-drift, rail-to-rail input/output operational amplifier optimized for high-precision signal conditioning in 24-V industrial systems. It delivers ±10 µV typical input offset voltage, 0.1 µV/°C max drift over –40°C to +125°C, 750 kHz gain-bandwidth, and operates from 4.5 V to 24 V supply. Its key role is high-side current shunt monitoring and precision sensor signal amplification in battery-powered or DC/DC converter feedback loops.
For engineers reviewing the TLV2186IDSGT datasheet, TLV2186IDSGT pinout, TLV2186IDSGT application, or TLV2186IDSGT equivalent, this page provides verified specifications, package mapping (WSON-8), functional pin definitions, real-world use cases in flow transmitters and electricity meters, and two validated alternative parts with documented technical and application differences.
Technical Context
The TLV2186IDSGT implements a chopper-stabilized zero-drift architecture with integrated notch filtering to eliminate flicker noise and achieve near-zero long-term offset drift. Its rail-to-rail input stage extends common-mode range to (V–) – 0.2 V and (V+) + 0.2 V, enabling direct high-side sensing without level-shifting circuitry.
It features EMI rejection ratio (EMIRR) of 88.9 dB at 2.4 GHz and 95.5 dB at 5 GHz, phase-reversal protection, and MUX-friendly inputs tolerant of fast input transients. The device is unity-gain stable and supports capacitive loads up to 1000 pF with appropriate isolation resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | ±10 µV typical - enables <10 ppm error in 1-V full-scale precision measurement systems |
| Offset Drift | ±0.1 µV/°C max - ensures <1.5 µV total drift across –40°C to +125°C operating range |
| Supply Range | 4.5 V to 24 V - supports single-supply operation in 12-V and 24-V industrial rails without split supplies |
| Gain-Bandwidth Product | 750 kHz - sufficient for closed-loop bandwidths up to ~100 kHz in G = 10 configurations |
| Quiescent Current | 90 µA per amplifier - allows dual-opamp precision signal chain in battery-powered instruments with multi-year runtime |
| CMRR | 126 dB min at ±2.25 V - rejects >4 million:1 common-mode interference in low-level sensor interfaces |
| Output Swing | Within 20 mV of rails (no load) - preserves dynamic range in rail-to-rail output stages driving ADC reference buffers |
Pinout & Package
The TLV2186IDSGT is housed in an 8-pin WSON package (2.00 mm × 2.00 mm) with exposed thermal pad, optimized for space-constrained PCB layouts and thermal performance (RθJB = 36.8 °C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT A | Output channel A | Amplified output of channel A; rail-to-rail capable; requires local 0.1-µF decoupling to V– |
| 2 - –IN A | Inverting input channel A | Differential input node; chopper-modulated; sensitive to EMI - shielded routing recommended |
| 3 - +IN A | Noninverting input channel A | Primary high-impedance input; EMIRR-tested node; connects directly to shunt resistor or sensor |
| 4 - V– | Negative supply | Ground reference for single-supply operation; thermal pad must be soldered to PCB ground plane |
| 5 - +IN B | Noninverting input channel B | Independent second channel input; identical specs to +IN A; supports dual-sensor or differential pair use |
| 6 - –IN B | Inverting input channel B | Second channel inverting input; shares same zero-drift core architecture as channel A |
| 7 - OUT B | Output channel B | Independent output; no crosstalk specified - usable for dual-path signal conditioning or feedback control |
| 8 - V+ | Positive supply | 24-V tolerant input; accepts 4.5–24 V; requires 0.1-µF + 10-µF parallel decoupling per TI layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input beyond supply rails | Accepts common-mode voltage from (V–) – 0.2 V to (V+) + 0.2 V - eliminates need for external level shifters in high-side current sensing |
| EMI rejection at RF bands | EMIRR +IN = 95.5 dB at 5 GHz - suppresses offset shifts induced by Wi-Fi 5/6, Bluetooth, and cellular interference in dense PCBs |
| No phase reversal | Output saturates cleanly into rails when input exceeds linear range - prevents system latch-up in overvoltage fault conditions |
| Zero-drift architecture | Chopper + auto-zero hybrid design - achieves ultra-low 1/f noise and eliminates manual calibration in field-deployed instrumentation |
| MUX-friendly inputs | Withstands fast input transients without latch-up or output disturbance - suitable for multiplexed sensor arrays with shared op-amp resources |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2188AIDR | Higher quiescent current (410 µA vs 90 µA); lower GBW (2 MHz vs 750 kHz); same zero-drift architecture and 0.003 µV/°C drift | Better for wideband active filters; less suitable for ultra-low-power battery systems | Select OPA2188AIDR when bandwidth >1 MHz is required and power budget allows >4× higher IQ |
| AD8628ARZ-REEL7 | Single-channel only; higher offset (±25 µV); same 0.1 µV/°C drift; 2.5-MHz GBW; 1.5 mA IQ | Requires two devices for dual-channel function; better for high-speed, low-noise sensor interfaces where power is secondary | Choose AD8628ARZ-REEL7 for single-channel, high-GBW precision needs with tighter board area constraints than SOIC-8 |
Compared with TLV2186IDSGT, OPA2188AIDR trades 4.5× higher quiescent current for 2.7× greater bandwidth, while AD8628ARZ-REEL7 offers higher speed but doubles component count and power draw for dual-channel use - making TLV2186IDSGT optimal for space- and power-constrained dual-channel precision sensing.

FAQ
What is the maximum supply voltage rating for TLV2186IDSGT?
The TLV2186IDSGT has an absolute maximum supply voltage (VS) of 26 V, with recommended operation from 4.5 V to 24 V. Exceeding 26 V risks permanent damage per JEDEC stress ratings. At 24 V, it maintains full rail-to-rail input/output swing and specified offset drift performance across –40°C to +125°C.
Does TLV2186IDSGT support true rail-to-rail input beyond the supply rails?
Yes - the TLV2186IDSGT accepts input common-mode voltages from (V–) – 0.2 V to (V+) + 0.2 V, verified per datasheet Section 6.5. This allows direct connection to high-side shunts in 24-V systems without external level-shifting components, a key differentiator versus standard rail-to-rail op amps.
What is the thermal pad connection requirement for TLV2186IDSGT?
The exposed thermal pad on the TLV2186IDSGT (WSON-8 package) must be soldered to a PCB copper pour connected to V– (ground in single-supply configurations). Per TI's thermal metrics, this reduces junction-to-board resistance to 36.8 °C/W - critical for maintaining <125°C junction temperature at 90 µA per amplifier under continuous operation.
How does TLV2186IDSGT handle EMI in noisy industrial environments?
The TLV2186IDSGT integrates on-die EMI filtering and achieves EMIRR +IN of 95.5 dB at 5 GHz. This measured rejection ratio prevents RF rectification-induced offset shifts from Wi-Fi, Bluetooth, or cellular signals - confirmed via TI's standardized test configuration (Figure 41, SBOS947A) and validated in field deployments in factory automation controllers.
Is TLV2186IDSGT suitable for multiplexed sensor applications?
Yes - the TLV2186IDSGT is explicitly characterized as "MUX-friendly" in its datasheet (Section 7.3.3), with input architecture designed to tolerate fast input transients and channel switching without output disturbance or latch-up. Its low input bias current (0.1 nA typ) also minimizes crosstalk errors in high-impedance multiplexed sensor arrays.
