Product details
Overview
TLV4113CDR from Texas Instruments is a dual-channel, rail-to-rail output operational amplifier with shutdown control, delivering >300 mA output current per channel at 5 V, unity-gain bandwidth of 2.7 MHz, slew rate of 1.5 V/µs, and supply current of 700 µA per channel across 2.5 V to 6 V operation - used in high-current buffer and coil driver applications.
For engineers reviewing the TLV4113CDR datasheet, TLV4113CDR pinout, TLV4113CDR application, or TLV4113CDR equivalent, key selection considerations include its dual-channel high-output-drive capability, thermal performance in DGQ package, shutdown logic thresholds (VON = 3.8 V @ VDD = 5 V), and guaranteed operation from 0°C to 70°C.
Technical Context
The TLV4113CDR integrates two independent high-output-current op-amps with individual shutdown inputs (1SHDN, 2SHDN), rail-to-rail output swing, and internal compensation for unity-gain stability with 100 Ω load and 10 pF capacitance. Its architecture supports fast turn-on (1 µs) and turn-off (3.3 µs) transitions during shutdown control.
It operates from single-supply 2.5 V to 6 V, features CMRR ≥63 dB (VDD = 3 V), PSRR ≥65 dB, and maintains low THD+N (0.035% @ AV = 10, f = 100 Hz) - optimized for driving capacitive and moderate-resistive loads without external compensation under defined thermal conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Dual - enables independent signal conditioning or parallel drive paths in compact space-constrained designs. |
| Output Current | ±320 mA @ VDD = 5 V - sufficient to directly drive solenoids, relays, or power MOSFET gates without external buffers. |
| Rail-to-Rail Output | Swings within 100 mV of rails @ 100 mA - maximizes dynamic range in low-voltage systems (e.g., 3.3 V or 5 V supplies). |
| Unity-Gain Bandwidth | 2.7 MHz - supports stable closed-loop operation up to ~200 kHz with gain ≥10 while maintaining phase margin ≥66°. |
| Slew Rate | 1.5 V/µs @ VDD = 5 V - enables clean 1-VPP step response in <1 µs, suitable for pulse amplification and active filtering. |
| Shutdown Current | 10 µA max per channel - reduces system standby power in battery-powered instrumentation and portable equipment. |
| Supply Voltage Range | 2.5 V to 6 V - compatible with Li-ion, USB, and industrial 3.3 V/5 V rails without level-shifting circuitry. |
Pinout & Package
The TLV4113CDR is packaged in a 10-pin MSOP PowerPAD™ (DGQ) thermally enhanced surface-mount package with exposed thermal pad electrically isolated from all terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Channel 1 output | Delivers high-current rail-to-rail output; requires series RNULL ≤20 Ω for CL >1 nF to maintain stability. |
| 1IN− | Channel 1 inverting input | High-impedance node (1000 GΩ); bias current ≤50 pA (C-suffix) enables precision transimpedance configurations. |
| 1IN+ | Channel 1 non-inverting input | Common-mode range extends to VDD − 1.5 V - supports direct sensing of signals near supply rail. |
| GND | Analog ground reference | Must connect thermal pad to PCB ground plane via five 13-mil vias for optimal θJA = 52.3°C/W. |
| 1SHDN | Channel 1 shutdown control | Active-low logic: VOFF ≤1.65 V @ VDD = 5 V disables amplifier and places output in high-Z state. |
| VDD+ | Positive supply input | Accepts 2.5–6 V; absolute max 7 V; PSRR ≥70 dB ensures immunity to supply ripple in noisy environments. |
| 2OUT | Channel 2 output | Independent high-current output; crosstalk ≤−60 dB @ 100 kHz allows simultaneous use without coupling. |
| 2IN− | Channel 2 inverting input | Matched offset voltage drift (3 µV/°C) enables dual-channel matched gain stages in sensor front-ends. |
| 2IN+ | Channel 2 non-inverting input | Same VICR as Channel 1 - supports dual-sensor differential amplification with common-mode rejection ≥68 dB. |
| 2SHDN | Channel 2 shutdown control | Independent enable/disable control permits dynamic channel gating in multi-stage power management circuits. |
Key Features
| Feature | Design Value |
|---|---|
| High-output-drive capability | Delivers ±320 mA per channel at 5 V - eliminates need for discrete output transistors in relay/solenoid drivers. |
| Thermally enhanced PowerPAD™ | θJA = 52.3°C/W enables 2.39 W power dissipation - supports continuous 350 mA output at TA = 125°C. |
| Individual shutdown control | Two dedicated SHDN pins allow independent channel disable - reduces quiescent current to 10 µA per channel. |
| Rail-to-rail output swing | Output reaches within 100 mV of VDD and GND at 100 mA - preserves full signal swing in 3.3 V data acquisition systems. |
| Low THD+N | 0.035% @ 100 Hz, AV = 10 - meets audio-grade line-driver requirements without external feedback compensation. |
| Fast shutdown timing | Turn-off time = 3.3 µs - enables precise pulse-width control in switched-mode analog signal routing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-output-drive operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC072CDR | No shutdown function; lower output current (±50 mA); higher supply current (1.5 mA/channel); SOIC-8 only. | Lacks independent channel disable; unsuitable for battery-critical or dynamic power-gating systems. | Select when cost sensitivity outweighs power efficiency and output drive needs. |
| OPA2544U | Higher output current (±500 mA); wider supply range (±4 V to ±18 V); no rail-to-rail output; larger SOIC-14 package. | Requires dual supply; not compatible with single-ended 3.3 V/5 V systems; exceeds thermal budget in same PCB area. | Select for bipolar high-power applications where rail-to-rail output is unnecessary and dual supply is available. |
Compared with TLC072CDR and OPA2544U, the TLV4113CDR uniquely combines dual-channel rail-to-rail output, per-channel shutdown, and 320 mA drive in a thermally optimized 10-pin MSOP - enabling compact, low-quiescent-power, single-supply high-current analog interfaces.

FAQ
What is the maximum continuous output current per channel for TLV4113CDR at 125°C ambient?
The TLV4113CDR delivers up to 350 mA continuous output current per channel at TA = 125°C when mounted on a PCB with proper PowerPAD™ thermal design (θJA = 52.3°C/W). This rating assumes junction temperature remains ≤105°C; exceeding this requires derating per the dissipation rating table in the datasheet. The TLV4113CDR achieves this via its DGQ package's low thermal impedance and internal current-limiting architecture.
Does TLV4113CDR support rail-to-rail input common-mode range?
No, the TLV4113CDR supports rail-to-rail *output* swing but has a limited input common-mode range of 0 V to VDD − 1.5 V. For example, at VDD = 5 V, the valid input range is 0 V to 3.5 V. This means the TLV4113CDR cannot accurately amplify signals near the positive rail without external level-shifting. Its input stage is optimized for high output drive, not full-range input capture.
Can TLV4113CDR drive a 1000-pF capacitive load without oscillation?
Driving 1000-pF directly on the TLV4113CDR output risks instability due to reduced phase margin. The datasheet recommends inserting a series resistor (RNULL ≤20 Ω) between the output and capacitive load to restore ≥66° phase margin. This snubber network isolates the amplifier's output stage from the capacitive reactance, preventing high-frequency ringing observed in pulse-response tests. The TLV4113CDR's stability is validated only with RNULL for CL >1 nF.
What is the shutdown logic threshold voltage for TLV4113CDR at 5 V supply?
At VDD = 5 V, the TLV4113CDR's shutdown pin activates (disables amplifier) when voltage falls to ≤1.65 V (VOFF) and deactivates (enables amplifier) when voltage rises to ≥3.8 V (VON). These thresholds provide 2.15 V hysteresis to reject noise on the SHDN line. The TLV4113CDR requires an external pull-up resistor to VDD to ensure reliable enablement; floating SHDN pins may cause unintended shutdown due to leakage currents.
Is TLV4113CDR pin-compatible with other TLV411x variants in DGQ package?
Yes, the TLV4113CDR (DGQ-10) shares identical pinout with TLV4113IDGQ and TLV4113IDGQ - all use the same 10-pin MSOP PowerPAD™ layout with 1OUT, 1IN−, 1IN+, GND, 1SHDN, VDD+, 2OUT, 2IN−, 2IN+, 2SHDN. Temperature grade (C vs I) and reel packaging (R suffix) do not affect pin mapping. However, TLV4112 variants lack shutdown pins and use different 10-pin assignments - TLV4113CDR is not pin-compatible with TLV4112DGN or TLV4112DGQ.
