Texas Instruments TLV4113CD

Overview

TLV4113CD 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 requiring robust drive capability and thermal efficiency.

For engineers reviewing the TLV4113CD datasheet, TLV4113CD pinout, TLV4113CD application, or TLV4113CD equivalent, key selection considerations include confirmed dual-channel architecture, active shutdown functionality (1SHDN/2SHDN), MSOP-10 package thermal performance, rail-to-rail output swing under load, and validated 300 mA continuous output current at TJ ≤ 105°C.

Technical Context

The TLV4113CD integrates two independent high-output-drive op-amps with dedicated shutdown inputs (Pin 5 and Pin 10), enabling per-channel power gating. Its internal architecture supports rail-to-rail output swing down to within 200 mV of rails at 100 mA load (VDD = 5 V) and maintains stability with capacitive loads up to 1 nF when using RNULL compensation.

It operates across 0°C to 70°C (C-suffix), features input offset voltage ≤3.5 mV (full range), CMRR ≥63 dB (VDD = 3 V), and PSRR ≥65 dB - optimized for single-supply systems where headroom and output drive dominate over ultra-low noise or precision DC performance.

Key Specifications

Pinout & Package

The TLV4113CD is packaged in a 10-pin MSOP PowerPAD™ (DGQ) thermally enhanced surface-mount package, featuring an exposed thermal pad electrically isolated from all terminals and requiring PCB soldering for optimal thermal dissipation (θJA = 52.3°C/W).

The following parts are listed as comparable options for similar high-output-drive op-amp applications.

Compared with TLV4113IDGQ, the TLV4113CD offers lower cost and sufficient performance for commercial-temperature applications, while OPA2544T trades shutdown capability and thermal efficiency for higher current and bipolar operation - making TLV4113CD optimal for cost-sensitive, battery-aware, single-supply industrial modules.

FAQ

What is the maximum continuous output current specification for TLV4113CD at 25°C?

The TLV4113CD delivers ±320 mA per channel at VDD = 5 V and TA = 25°C under typical conditions. However, continuous output current is thermally limited: at TJ ≤ 105°C, it supports 350 mA RMS per channel; at TJ ≤ 150°C, this drops to 110 mA. The MSOP-10 DGQ package's low θJA (52.3°C/W) enables sustained high-current operation when properly heatsinked to a ground plane via the PowerPAD™ thermal pad.

Does TLV4113CD support rail-to-rail input operation?

No, the TLV4113CD does not support rail-to-rail input. Its common-mode input voltage range is specified as 0 V to VDD − 1.5 V - meaning at VDD = 5 V, inputs must stay within 0 V to 3.5 V. This limitation is intentional to preserve input stage headroom and ensure stable operation with high output drive. For true rail-to-rail input capability, alternative devices like the OPA2333 or TLV9062 would be required.

How does the shutdown feature operate on TLV4113CD, and what is the logic polarity?

The TLV4113CD has two independent active-low shutdown inputs: Pin 5 (1SHDN) and Pin 10 (2SHDN). When either pin is pulled below V_OFF (0.9 V at VDD = 3 V or 1.65 V at VDD = 5 V), the corresponding amplifier channel disables - its output enters high-impedance state and supply current drops to ≤15 µA per channel. A pullup resistor to VDD is required to ensure reliable enablement; floating SHDN pins risk parasitic leakage-induced unintended shutdown.

Can TLV4113CD drive capacitive loads, and what is the recommended compensation method?

Yes, TLV4113CD can drive capacitive loads up to 1 nF stably without external compensation. For loads exceeding 1 nF, Texas Instruments recommends inserting a series resistor (RNULL) between the output and load - typically ≤20 Ω - to isolate the capacitive reactance from the amplifier's output stage. This preserves phase margin (>66°) and prevents ringing or oscillation, as verified in Figure 27 of the SLOS289E datasheet. Layout best practices include short traces and minimized parasitic capacitance.

What is the thermal pad connection requirement for the TLV4113CD MSOP-10 (DGQ) package?

The exposed thermal pad on the TLV4113CD's MSOP-10 DGQ package must be soldered to a PCB copper area connected to GND - it is electrically isolated from all pins but serves as the primary thermal conduction path. TI recommends five 13-mil vias under the pad, connected solidly (not webbed) to an internal ground plane. Failure to solder the thermal pad increases θJA from 52.3°C/W to >120°C/W, risking thermal shutdown or accelerated electromigration failure at >100 mA continuous load.
