Texas Instruments TLV4113IN

Overview

TLV4113IN 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. It operates from 2.5 V to 6 V and supports industrial temperature range (−40°C to 125°C), enabling high-current buffer and coil driver applications in motor control and sensor excitation circuits.

For engineers reviewing the TLV4113IN datasheet, TLV4113IN pinout, TLV4113IN application, or TLV4113IN equivalent, key selection considerations include its dual-channel high-output-drive capability, thermal performance in PDIP-14 package, shutdown functionality with 1 µs turn-on time, and rail-to-rail output swing under heavy load conditions.

Technical Context

The TLV4113IN integrates two independent high-output-drive op-amps with dedicated shutdown inputs (1SHDN and 2SHDN), each capable of sourcing/sinking up to ±320 mA at 5 V while maintaining rail-to-rail output swing. Its internal architecture supports stable operation into capacitive loads ≥1 nF when used with RNULL series output resistors.

It features low input offset voltage (max 3500 µV), CMRR of 68 dB at 5 V, PSRR of 79 dB, and THD+N of 0.15% at AV = 100 - optimized for precision analog signal conditioning where output drive strength and power efficiency coexist.

Key Specifications

Pinout & Package

The TLV4113IN is housed in a 14-pin plastic DIP (PDIP-14) package with through-hole mounting and GND-connected thermal pad on bottom side (electrically isolated). Pin 1 is 1OUT; pins 5 and 13 are NC; pins 6 and 14 are SHDN inputs for Channel 1 and Channel 2 respectively.

FAQ

What is the maximum continuous output current per channel for TLV4113IN at 125°C ambient?

The TLV4113IN supports 110 mA continuous output current per channel at TJ ≤ 150°C. At TA = 125°C and using the N-package (θJA = 78°C/W), junction temperature remains within limit only if power dissipation stays ≤320.5 mW - corresponding to ~110 mA into a 5 V load. Derating is mandatory above 105°C junction temperature per datasheet Dissipation Rating Table.

Does TLV4113IN require external components to drive a 10 nF capacitive load?

Yes, TLV4113IN requires a series resistor (RNULL) between output and capacitive load when CL > 1 nF. For 10 nF, a 20 Ω RNULL restores phase margin and prevents oscillation, as confirmed by Figure 17 (Phase Margin vs Capacitive Load) and Application Information section on driving capacitive loads. This applies to both channels independently.

What is the function of Pin 5 (1SHDN) and Pin 13 (2SHDN) on TLV4113IN?

Pin 5 (1SHDN) and Pin 13 (2SHDN) are active-low shutdown controls for Channel 1 and Channel 2 respectively. When pulled ≤0.9 V (at VDD = 3 V) or ≤1.65 V (at VDD = 5 V), each channel enters shutdown: supply current drops to ≤15 µA per channel and output goes high-impedance. Both pins must be pulled high (≥2.1 V at 3 V or ≥3.8 V at 5 V) to enable operation of TLV4113IN.

Can TLV4113IN operate from a 2.7 V supply while delivering 200 mA output current?

Yes, TLV4113IN operates from 2.5 V to 6 V and delivers ±220 mA per channel at VDD = 3 V (per Electrical Characteristics table). At 2.7 V, output swing compresses but remains functional: VOH ≥ 2.4 V and VOL ≤ 0.4 V at 100 mA (Figure 4/5), supporting 200 mA with appropriate thermal design. The PDIP-14 package's 1600 mW rating at 25°C ambient allows this under controlled conditions.

Is the thermal pad on TLV4113IN electrically connected to any pin?

No, the thermal pad on TLV4113IN (N-package) is electrically isolated from all terminals, as explicitly stated in Figure 30 note A and Application Information section "general PowerPAD design considerations". It must be soldered to PCB ground plane solely for thermal conduction - no electrical connection is made or required.
