Product details
Overview
TLC073CDR from Texas Instruments is a dual-channel, wide-bandwidth (10 MHz), high-output-drive (±55 mA) single-supply operational amplifier in SOIC-14 package, featuring 16 V/μs slew rate, 7 nV/√Hz input voltage noise, and ultralow-power shutdown mode (125 μA/channel). It operates from 4.5 V to 16 V and is used in precision audio line drivers, industrial sensor signal conditioning, and active filter stages requiring rail-to-rail output swing and robust load driving.
For engineers reviewing the TLC073CDR datasheet, TLC073CDR pinout, TLC073CDR application, or TLC073CDR equivalent, this page delivers verified electrical specs, SOIC-14 terminal mapping, real-world use cases in audio and instrumentation, and two validated alternative op-amps with documented functional trade-offs for design flexibility.
Technical Context
The TLC073CDR employs TI's patented LBC3 BiCMOS process, integrating a low-noise CMOS front end (1000 GΩ differential input resistance, 7 nV/√Hz noise) with a high-current bipolar output stage capable of ±55 mA drive into heavy loads. Its dual-channel architecture shares a common shutdown control (pin 1/8), enabling synchronized power gating across both amplifiers without inter-channel crosstalk degradation.
Designed for single-supply operation, it supports rail-to-rail output swing (within 0.5 V of rails at 50 mA) and a wide common-mode input range (0.5 V to VDD − 0.8 V), making it suitable for DC-coupled signal chains in 5 V and 12 V systems. The device maintains stable phase margin (>32°) up to 50 pF capacitive load without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz gain-bandwidth product - enables stable unity-gain buffer or 10× gain amplification up to 1 MHz. |
| Slew Rate | +16 V/μs / −19 V/μs - supports fast settling (0.17 μs to 0.01%) for pulse and video signals. |
| Output Drive | ±55 mA per channel - drives 600 Ω audio loads or multiple logic inputs directly without external buffers. |
| Input Offset Voltage | 390 μV typical (25°C), ≤2 mV max over full temperature range - ensures <1 mV error in 10× gain sensor interfaces. |
| Supply Range | 4.5 V to 16 V single supply - compatible with 5 V microcontroller systems and 12 V industrial rails. |
| Shutdown Current | 125 μA/channel - reduces total system standby power by >93% vs active mode (1.9 mA/channel). |
| Input Noise | 7 nV/√Hz at 1 kHz - preserves SNR in low-level microphone preamp and strain gauge amplification. |
Pinout & Package
Package: SOIC-14 (D package), 8.65 mm × 3.91 mm, surface-mount, tape-and-reel (R suffix). Thermal resistance θJA = 122.3°C/W; rated for 1022 mW power dissipation at TA ≤ 25°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1/2SHDN | Active-high shutdown control for both channels; ≥2 V enables, ≤0.8 V disables (125 μA/channel quiescent). |
| 2 | 1IN− | Inverting input of Channel 1 - high-impedance CMOS node (1000 GΩ) for precision feedback networks. |
| 3 | 1IN+ | Non-inverting input of Channel 1 - accepts common-mode voltages from 0.5 V to VDD − 0.8 V. |
| 4 | GND | Analog ground reference - must be low-impedance star point for noise-sensitive applications. |
| 5 | 2IN+ | Non-inverting input of Channel 2 - electrically isolated from Channel 1; same CMVR as Pin 3. |
| 6 | 2IN− | Inverting input of Channel 2 - independent high-Z node; no internal connection to Channel 1. |
| 7 | 2OUT | Amplified output of Channel 2 - delivers ±55 mA into resistive or capacitive loads. |
| 8 | 1/2SHDN | Redundant shutdown input (tied internally to Pin 1); allows flexible PCB routing or logic-level translation. |
| 9 | 2OUT | No connection - unused pin in SOIC-14; not bonded or connected internally. |
| 10 | NC | No internal connection - mechanical placeholder; must remain unconnected on PCB. |
| 11 | VDD | Positive supply rail - accepts 4.5–16 V; bypass with 0.1 μF ceramic capacitor near pin. |
| 12 | 1OUT | Amplified output of Channel 1 - fully specified for drive strength, settling time, and THD+N. |
| 13 | 1IN− | No connection - duplicate of Pin 2; not bonded in SOIC-14 package. |
| 14 | 1IN+ | No connection - duplicate of Pin 3; not bonded in SOIC-14 package. |
Key Features
| Feature | Design Value |
|---|---|
| BiMOS Process Architecture | Combines CMOS input stage (ultra-low bias current: 100 pA typ) with bipolar output (high drive + low distortion). |
| Single-Supply Operation | Common-mode input range extends to 0.5 V above GND and within 0.8 V of VDD - eliminates level-shifting in 5 V systems. |
| Integrated Shutdown Control | Single logic input (Pins 1 & 8) disables both amplifiers simultaneously, reducing supply current to 125 μA total. |
| High Output Current | Delivers ±55 mA while maintaining <0.5 V saturation voltage - drives 600 Ω headphones or 4–20 mA loop transmitters. |
| Low Distortion Performance | THD+N = 0.005% at 1 kHz, 8 VPP, 10 kΩ load - meets Class AB audio and precision DAC output buffer requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, high-output-drive operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2350UA | Lower noise (5 nV/√Hz), lower supply current (4.9 mA/ch), but reduced output drive (±30 mA) and narrower supply range (2.7–5.5 V). | Better suited for battery-powered portable audio; unsuitable for 12 V industrial loads or 600 Ω driving. | Select when ultra-low noise and low power dominate over output current and supply flexibility. |
| LMH6624MF/NOPB | Higher bandwidth (1.5 GHz), higher slew rate (360 V/μs), but much higher supply current (12.5 mA/ch) and no shutdown mode. | Targeted at RF/IF signal chains and high-speed data acquisition; overqualified for audio/sensor apps with excessive power cost. | Select only for >100 MHz small-signal amplification; avoid for DC-coupled or power-constrained designs. |
Compared with OPA2350UA and LMH6624MF/NOPB, the TLC073CDR uniquely balances 10 MHz bandwidth, ±55 mA drive, 125 μA shutdown, and 4.5–16 V operation - making it the optimal choice for cost-sensitive, mixed-voltage industrial and audio systems requiring both precision and robustness.

FAQ
What is the operating temperature range for the TLC073CDR?
The TLC073CDR is rated for commercial temperature operation from 0°C to 70°C, as indicated by the "C" suffix in the part number. It meets all electrical specifications across this range, including input offset voltage (≤2 mV), supply current (≤3.5 mA/channel), and output drive (±55 mA) at 70°C ambient.
Does the TLC073CDR support rail-to-rail input or output?
The TLC073CDR supports rail-to-rail output swing (within 0.5 V of VDD and GND at full load) but not rail-to-rail input. Its common-mode input voltage range is specified from 0.5 V to VDD − 0.8 V, meaning it cannot accept signals at the negative rail (GND) or within 0.8 V of VDD without performance degradation.
How does the shutdown function work on the TLC073CDR?
The TLC073CDR uses an active-high shutdown control on Pins 1 and 8. When SHDN ≥ 2 V, both amplifiers operate normally. When SHDN ≤ 0.8 V, supply current drops to 125 μA per channel (250 μA total), and outputs enter high-impedance state. Turn-on/off times are 0.15 μs and 1.3 μs respectively at 25°C.
Can the TLC073CDR drive a 600 Ω load at 10 VPP?
Yes - at VDD = 12 V, the TLC073CDR delivers 10.4 VPP into 600 Ω with THD+N ≤ 0.022% at 1 kHz. Its ±55 mA output current capability ensures full swing without clipping or thermal foldback, validated in TI's Figure 32 and electrical characteristics tables.
Is the TLC073CDR pin-compatible with other devices in the TLC07x family?
No - the TLC073CDR (SOIC-14) has a unique pinout among dual-channel variants. TLC072CDR uses SOIC-8 with no shutdown pins, while TLC073CDR dedicates Pins 1/8 to shutdown and Pins 9/10 to NC. Direct substitution requires PCB layout revision and verification of shutdown logic integration.
