Texas Instruments TLV4110CDR

Overview

TLV4110CDR from Texas Instruments is a single-channel, rail-to-rail output operational amplifier with shutdown capability, delivering >300 mA continuous output current at 5 V, 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 serves as a high-current buffer or coil driver in portable instrumentation and industrial actuator interfaces.

For engineers reviewing the TLV4110CDR datasheet, TLV4110CDR pinout, TLV4110CDR application, or TLV4110CDR equivalent, key selection criteria include verified 300 mA drive capability under thermal constraints, confirmed shutdown logic thresholds (V_ON = 2.1 V @ 3 V, V_OFF = 0.9 V @ 3 V), SOIC-8 package compatibility, and validated performance over 0°C to 70°C commercial temperature range.

Technical Context

The TLV4110CDR integrates a robust output stage capable of sourcing/sinking ±320 mA at 5 V while maintaining rail-to-rail swing and low distortion (THD+N = 0.035% @ 100 Hz, RL = 100 Ω, AV = 10). Its internal shutdown circuit reduces supply current to ≤15 µA per channel when SHDN is pulled low, placing outputs in high-impedance state.

Designed for thermally demanding loads, it features a SOIC-8 package with θ_JA = 176°C/W and RMS power limit of 350 mW - requiring careful PCB layout for sustained >200 mA operation. The device exhibits stable phase margin (66°) with 100 Ω load and 10 pF capacitance, supporting fast settling (0.7 µs to 0.1%).

Key Specifications

Pinout & Package

FAQ

What is the maximum continuous output current specification for TLV4110CDR?

The TLV4110CDR delivers ±320 mA continuous output current at 5 V supply, measured at 0.5 V from either rail. This rating applies under thermal conditions where junction temperature remains ≤105°C. For sustained operation above 200 mA, proper PCB copper pour and thermal vias beneath the SOIC-8 package are required to maintain reliability.

Does TLV4110CDR support rail-to-rail input operation?

No, TLV4110CDR does not support rail-to-rail input. Its common-mode input voltage range is specified as 0 V to (V_DD − 1.5 V), meaning it cannot accept signals within 1.5 V of the positive rail. However, it does provide true rail-to-rail output swing, operating within 100 mV of both supply rails at 100 mA load.

How does the shutdown feature of TLV4110CDR behave during power-up?

TLV4110CDR enters shutdown mode when SHDN is left floating or pulled below 0.9 V (V_OFF). During power-up, an external pullup resistor (typically 10–100 kΩ to V_DD) is mandatory to ensure SHDN rises above 2.1 V (V_ON) before the amplifier becomes active - preventing undefined output states or latch-up.

Can TLV4110CDR drive capacitive loads without external compensation?

TLV4110CDR remains stable with ≤10 pF capacitive loads when driving 100 Ω resistive loads. For loads >1 nF, a series resistor (R_NULL ≤20 Ω) must be added between OUT and the capacitive load to preserve phase margin and prevent ringing. This is documented in Figure 27 of the SLOS289E datasheet.

What is the thermal resistance (θ_JA) of TLV4110CDR in its SOIC-8 package?

The TLV4110CDR in SOIC-8 (D) package has a junction-to-ambient thermal resistance (θ_JA) of 176°C/W, as measured on a standard JEDEC 2-layer test board. This value assumes minimal copper area; adding thermal vias and ground-plane connections can reduce effective θ_JA by up to 30%, enabling higher continuous output current.
