Product details
Overview
TLV4112IDR from Texas Instruments is a dual-channel, rail-to-rail output operational amplifier optimized for high-current buffer and coil driver applications. It delivers >300 mA per channel at 5 V, features 2.7 MHz unity-gain bandwidth, 1.5 V/µs slew rate, and operates from 2.5 V to 6 V supply with 700 µA per channel quiescent current. It is specified for −40°C to 125°C industrial temperature range and housed in an 8-pin SOIC (D) package.
For engineers reviewing the TLV4112IDR datasheet, TLV4112IDR pinout, TLV4112IDR application, or TLV4112IDR equivalent, key selection criteria include output drive capability (>300 mA), thermal performance in SOIC vs PowerPAD packages, shutdown absence (TLV4112 lacks SHDN pin), rail-to-rail output swing, and stability with capacitive loads up to 1 nF without external compensation.
Technical Context
The TLV4112IDR employs a robust output stage capable of sourcing/sinking ±320 mA at 5 V while maintaining rail-to-rail output swing down to within 200 mV of each rail under 100 mA load. Its 2.7 MHz gain-bandwidth product and 1.5 V/µs slew rate support medium-speed closed-loop configurations such as active filters and precision buffers.
Designed for single-supply operation, it accepts common-mode input voltages from ground to VDD−1.5 V and exhibits 63–68 dB CMRR across 0–4 V input range. The device has no internal shutdown function-unlike TLV4110/TLV4113-and its SOIC-8 package (D) offers θJA = 176°C/W, limiting continuous RMS output power to 350 mW at TA ≤ 25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Dual - enables independent signal conditioning paths in compact space-constrained designs. |
| Output Drive | >300 mA per channel - supports direct driving of solenoids, relays, and low-impedance transducers without external boost stages. |
| Rail-to-Rail Output | Swings within 200 mV of rails at 100 mA - maximizes dynamic range in 3.3 V or 5 V systems with limited headroom. |
| Unity-Gain Bandwidth | 2.7 MHz - sufficient for audio preamps, sensor signal amplification, and medium-speed feedback loops. |
| Slew Rate | 1.5 V/µs - ensures <1.3 µs settling to 0.01% for 1 V step, suitable for pulse amplification and fast-settling buffers. |
| Supply Voltage Range | 2.5 V to 6 V - compatible with Li-ion, USB, and industrial 5 V rails; avoids need for LDO regulation in many cases. |
| Quiescent Current | 700 µA per channel - enables always-on operation in battery-backed instrumentation with minimal standby drain. |
Pinout & Package
TLV4112IDR is packaged in an 8-pin SOIC (D) surface-mount package with exposed leadframe not connected internally (non-PowerPAD variant). Thermal performance is governed by θJA = 176°C/W, requiring careful PCB copper area allocation for >350 mW continuous dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Channel 1 output | High-current output node; capable of ±320 mA at 5 V; requires local decoupling and thermal relief on PCB. |
| 1IN− | Channel 1 inverting input | Differential input terminal; bias current <500 pA allows high-impedance feedback networks. |
| 1IN+ | Channel 1 non-inverting input | Differential input terminal; common-mode range extends to GND and VDD−1.5 V. |
| GND | Analog ground reference | Primary return path for both channels; must be low-impedance and isolated from digital ground. |
| VDD | Positive supply rail | Single supply input (2.5–6 V); bypass capacitor (0.1 µF ceramic + 10 µF tantalum) required at pin. |
| 2OUT | Channel 2 output | Independent high-current output; electrically identical to 1OUT; no crosstalk degradation above −60 dB @ 100 kHz. |
| 2IN− | Channel 2 inverting input | Matched to 1IN−; offset voltage drift ≤3 µV/°C supports stable DC-coupled multi-stage gain blocks. |
| 2IN+ | Channel 2 non-inverting input | Matched to 1IN+; enables dual-sensor differential amplification or parallel channel buffering. |
Key Features
| Feature | Design Value |
|---|---|
| High-output-current architecture | Delivers >300 mA per channel continuously - eliminates need for discrete MOSFET followers in coil driver and LED array interfaces. |
| Rail-to-rail output swing | Maintains ≥93% of full-scale output voltage swing at 100 mA load - preserves SNR in low-voltage data acquisition front-ends. |
| Low quiescent current | 700 µA per channel at 25°C - enables integration into always-on sensor nodes with multi-year battery life at 3.3 V. |
| Stable with capacitive loads | Phase margin ≥66° with 10 pF load - supports direct connection to ADC input capacitors and long cables without series isolation resistor. |
| Industrial temperature grade | Specified from −40°C to 125°C - qualified for under-hood automotive, motor control, and factory automation environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-output-current op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2544TJ | Higher output current (±500 mA), wider supply (±15 V or 30 V single), but larger HTSSOP-20 package and 2.5 mA/ch quiescent current. | Targeted at high-voltage industrial actuation; unsuitable for space-constrained 3.3 V systems. | Select when >400 mA drive or bipolar supplies are required; avoid if low IQ or SOIC-8 footprint is mandatory. |
| LM7332MA | SOIC-8, rail-to-rail I/O, 60 mA output, 20 MHz GBW, 3.5 V/µs slew rate, 1.3 mA/ch IQ - lower drive but faster and more precise. | Optimized for high-fidelity signal chain; insufficient for solenoid or relay drivers. | Select for precision analog front-ends needing speed and accuracy; avoid where >100 mA sustained load current is needed. |
Compared with OPA2544TJ and LM7332MA, TLV4112IDR uniquely balances 300+ mA output, SOIC-8 footprint, 700 µA/ch IQ, and −40°C to 125°C rating - making it optimal for thermally constrained industrial actuators and always-on sensor interfaces where cost, size, and efficiency are co-prioritized.

FAQ
Does TLV4112IDR have a shutdown pin?
No, TLV4112IDR does not include a shutdown pin. Unlike TLV4110 and TLV4113, the TLV4112 variant omits the SHDN terminal entirely. This simplifies routing in dual-channel buffer designs but means power must be managed externally via supply enable or series FETs if low-power sleep states are required. The TLV4112IDR datasheet confirms absence of shutdown functionality across all package options (D, DGN, P).
What is the maximum continuous output current for TLV4112IDR in SOIC-8 package?
The maximum continuous RMS output current for TLV4112IDR in the SOIC-8 (D) package is 350 mA per channel at TJ ≤ 105°C, derating to 110 mA at TJ = 150°C. This limitation arises from θJA = 176°C/W and the 350 mW continuous power dissipation ceiling specified in the datasheet. Exceeding this requires thermal enhancement (e.g., copper pour, vias) or migration to MSOP PowerPAD (DGN) variant.
Can TLV4112IDR drive capacitive loads without oscillation?
Yes, TLV4112IDR remains stable with capacitive loads up to 10 pF without external compensation, exhibiting ≥66° phase margin. For loads >1 nF, TI recommends adding a 0–20 Ω series resistor (RNULL) between output and load to preserve stability. This design guidance is validated in Figure 17 (Phase Margin vs Capacitive Load) and Application Note section "Driving a Capacitive Load" in the TLV4112IDR datasheet.
What is the input common-mode voltage range for TLV4112IDR?
The input common-mode voltage range for TLV4112IDR is 0 V to VDD−1.5 V at room temperature, supporting ground-sensing capability but not true rail-to-rail input. At VDD = 5 V, this permits inputs from 0 V to 3.5 V; at VDD = 3.3 V, the upper limit is 1.8 V. This range is confirmed in the "Recommended Operating Conditions" table (page 3) and affects use in high-side current sensing or full-rail input buffer configurations.
Is TLV4112IDR pin-compatible with other TLV411x variants in SOIC-8?
Yes, TLV4112IDR shares identical SOIC-8 (D) pinout with TLV4111IDR and TLV4110IDR - all follow the standard dual-opamp configuration: 1OUT, 1IN−, 1IN+, GND, VDD, 2OUT, 2IN−, 2IN+. However, TLV4110IDR includes a SHDN pin (pin 5), which is NC on TLV4112IDR; thus, direct replacement requires verifying that pin 5 is left unconnected or tied to VDD/GND per system logic.
