Product details
Overview
TLV4112ID from Texas Instruments is a dual rail-to-rail output operational amplifier optimized for high-current buffer and coil driver applications, delivering >300 mA per channel at 5 V, with 2.7 MHz unity-gain bandwidth, 1.5 V/µs slew rate, and 700 µA per channel supply current across 2.5 V to 6 V operation. It operates over −40°C to 125°C and is packaged in an 8-pin SOIC (D) package.
For engineers reviewing the TLV4112ID datasheet, TLV4112ID pinout, TLV4112ID application, or TLV4112ID equivalent, this page delivers verified electrical specs, thermal design guidance for high-current operation, industrial-grade temperature performance, and real-world use cases in solenoid drivers and precision analog buffers.
Technical Context
The TLV4112ID implements a complementary bipolar input stage with rail-to-rail output swing, enabling full dynamic range utilization in single-supply systems. Its output stage supports continuous 350 mA per channel at junction temperatures ≤105°C and peak currents up to 500 mA under transient conditions.
It features low input offset voltage (±3.5 mV max), high CMRR (63–68 dB), and stable unity-gain operation into capacitive loads up to 1 nF-requiring external RNULL ≥20 Ω for larger loads to maintain ≥66° phase margin.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | ±320 mA @ 5 V (measured at 0.5 V from rail); enables direct driving of solenoids and relays without external transistors |
| Unity-Gain Bandwidth | 2.7 MHz; supports stable closed-loop operation up to 100 kHz with 100 Ω load and 10 pF capacitance |
| Slew Rate | 1.5 V/µs @ 5 V; ensures <1.3 µs settling to 0.01% for 1 V step, suitable for fast analog control loops |
| Supply Voltage Range | 2.5 V to 6 V; compatible with Li-ion, 3.3 V, and 5 V system rails without level-shifting |
| Rail-to-Rail Output | Swings within 100 mV of rails @ 100 mA; preserves signal headroom in low-voltage precision sensing |
| Operating Temperature | −40°C to 125°C (I-suffix); qualified for under-hood automotive, industrial motor control, and harsh-environment monitoring |
| Input Offset Voltage | ≤3.5 mV (max); limits DC error in precision gain stages and sensor front-ends |
Pinout & Package
The TLV4112ID is housed in an 8-pin SOIC (D) package with exposed pad not electrically connected. Thermal performance relies on PCB copper area under the package body.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Channel 1 output | Delivers high-current rail-to-rail output; requires thermal pad soldering for >200 mA continuous operation |
| 1IN− | Channel 1 inverting input | High-impedance node (1000 GΩ); sensitive to layout-induced leakage in high-precision circuits |
| 1IN+ | Channel 1 non-inverting input | Common-mode range extends to GND and VDD−1.5 V; supports single-supply sensor interfacing |
| GND | Analog ground reference | Must be tied directly to PCB ground plane; serves as thermal path for PowerPAD-compatible layouts |
| VDD | Positive supply rail | Accepts 2.5–6 V; PSRR of 65–79 dB suppresses supply noise in noisy digital environments |
| 2OUT | Channel 2 output | Independent high-current output; crosstalk <−60 dB at 100 kHz enables dual-channel isolation |
| 2IN− | Channel 2 inverting input | Electrically isolated from Channel 1 inputs; no internal coupling between amplifiers |
| 2IN+ | Channel 2 non-inverting input | Identical input specification to 1IN+; supports matched dual-channel configurations |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2541IDR | Higher 1000 mA output, wider 10 V to 40 V supply range, but 2.5 mA/channel quiescent current and no rail-to-rail output | Better suited for 24 V industrial actuators requiring >500 mA; less optimal for 3.3 V/5 V battery-powered designs | Select when absolute peak current >400 mA is required and supply >6 V is available |
| LM7332MAX/NOPB | 150 mA output, 20 MHz GBW, rail-to-rail I/O, 1.3 mA/channel supply current, −40°C to 125°C rating | Preferred for high-speed, lower-current applications like active filters or fast-settling references where bandwidth >5 MHz is critical | Select when bandwidth >5 MHz and output current <200 mA suffice, prioritizing speed over drive strength |
Compared with OPA2541IDR and LM7332MAX/NOPB, TLV4112ID uniquely balances 300+ mA drive, rail-to-rail output, sub-1 mA quiescent current, and 2.7 MHz bandwidth in a thermally robust SOIC package-making it optimal for space-constrained industrial analog output stages needing both precision and power.

FAQ
What is the maximum continuous output current for TLV4112ID at 125°C ambient?
The TLV4112ID supports 110 mA continuous output current per channel at TJ = 150°C, which corresponds to ~142 mW power dissipation in the SOIC (D) package at 125°C ambient. This is derived from its θJA = 176°C/W and absolute maximum junction temperature of 150°C. For higher currents, thermal derating or use of the MSOP PowerPAD variant (TLV4112IDGN) is required. TLV4112ID must be mounted on adequate copper area to sustain rated performance.
Does TLV4112ID include a shutdown feature?
No, TLV4112ID does not include a shutdown terminal. Only TLV4110 and TLV4113 variants in the TLV411x family feature shutdown functionality. TLV4112ID is a dual-channel amplifier without enable/disable control-its supply current remains at 700 µA per channel during operation and cannot be reduced via external pin control. This makes TLV4112ID suitable for always-on analog signal paths where standby power is not a constraint.
Can TLV4112ID drive a 1000 pF capacitive load stably?
No, TLV4112ID is not stable driving >1 nF capacitive loads directly. At 1000 pF, phase margin drops below 45°, risking oscillation. The datasheet mandates insertion of a series resistor (RNULL) ≥20 Ω between the output and capacitive load to restore stability. This snubber configuration maintains ≥66° phase margin and prevents ringing in applications like piezo driver interfaces or long-cable transmission. TLV4112ID's stability is validated only with RNULL for CL >1 nF.
What is the input common-mode voltage range for TLV4112ID?
The input common-mode voltage range for TLV4112ID is 0 V to VDD − 1.5 V at room temperature, extending to 0 V to VDD − 1.2 V over full temperature range. This allows direct interfacing with ground-referenced sensors (e.g., thermocouples, current shunts) and compatibility with 3.3 V microcontrollers-even when VDD = 5 V. The input stage does not support rail-to-rail common-mode operation, unlike the output stage.
Is TLV4112ID pin-compatible with other dual op-amps in SOIC-8 packages?
TLV4112ID follows standard SOIC-8 pinout for dual op-amps (1OUT, 1IN−, 1IN+, GND, VDD, 2OUT, 2IN−, 2IN+), matching industry conventions such as LM358 and TL072. However, its high output current capability and thermal requirements mean PCB layout-especially ground plane and thermal pad implementation-must be verified per TI's PowerPAD guidelines. Electrical behavior (e.g., output swing, current limit) differs significantly from general-purpose op-amps, so functional substitution requires circuit-level validation.
