Product details
Overview
TLC073CN from Texas Instruments is a dual-channel, single-supply operational amplifier featuring 10 MHz gain-bandwidth product, ±57 mA high-output drive capability, 16 V/μs positive slew rate, 7 nV/√Hz input voltage noise, and 1.9 mA per channel supply current. It operates from 4.5 V to 16 V and supports industrial temperature range (−40°C to 125°C), making it suitable for precision audio line drivers and sensor signal conditioning in automotive body control modules.
For engineers reviewing the TLC073CN datasheet, TLC073CN pinout, TLC073CN application, or TLC073CN equivalent, this page delivers verified electrical specifications, dual-opamp shutdown functionality, PDIP-14 package layout, BiMOS architecture advantages over TL07x predecessors, and real-world design considerations for single-supply rail-to-rail output interfacing.
Technical Context
The TLC073CN integrates a CMOS front end for ultralow input bias current (≤100 pA) and high input impedance with a bipolar output stage enabling ±57 mA drive into heavy loads. Its BiMOS LBC3 process delivers 300% higher bandwidth than TL07x while maintaining low 60 μV typical input offset voltage.
It features independent shutdown control for each amplifier (pins 1 and 13), wide common-mode input range (0.5 V to VDD−0.8 V), and robust phase margin (≥32°) with 50 pF capacitive load-enabling stable operation in active filters and transimpedance configurations without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 10 MHz - supports unity-gain-stable amplification up to 10 MHz, sufficient for audio band and medium-speed data acquisition. |
| Output drive current | ±57 mA - drives 600 Ω loads directly at 5 V supply, eliminating need for external buffer stages in line-driver applications. |
| Slew rate | 16 V/μs (SR+) / 19 V/μs (SR−) - enables fast settling of 1 V step signals in ≤0.39 μs (0.01% error), critical for pulse amplification. |
| Input voltage noise | 7 nV/√Hz at 1 kHz - low-noise performance preserves SNR in microphone preamps and strain-gauge signal chains. |
| Supply current per channel | 1.9 mA - enables dual-amplifier operation within 3.8 mA total, suitable for power-constrained industrial sensors. |
| Shutdown current per channel | 125 μA - reduces system standby power by >93% versus active mode, ideal for battery-backed instrumentation. |
| Input offset voltage | 60 μV typical - minimizes DC error in precision integrators and low-level transducer amplification without trimming. |
Pinout & Package
Package: 14-pin plastic DIP (PDIP), 0.3-inch width, through-hole mounting, RoHS-compliant lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Amplifier 1 shutdown | Active-high logic input; pulls IDD to 125 μA/channel when ≥2 V, disables output but retains input bias path. |
| 2 | Amplifier 1 inverting input | Differential input node with 1000 GΩ input resistance and 22.9 pF common-mode capacitance. |
| 3 | Amplifier 1 non-inverting input | High-impedance input referenced to GND; common-mode range extends from 0.5 V to VDD−0.8 V. |
| 4 | GND | Analog ground reference for both amplifiers and shutdown logic; must be low-impedance connection. |
| 5 | Amplifier 2 non-inverting input | Independent input for second op-amp; shares same CMRR (95 dB typ.) and input offset specs as Channel 1. |
| 6 | Amplifier 2 inverting input | Matches Pin 2 electrically; supports dual-channel differential instrumentation amplifier topologies. |
| 7 | Amplifier 2 output | Capable of sourcing/sinking ±57 mA; output impedance <0.25 Ω at 10 kHz ensures minimal gain error with reactive loads. |
| 8 | VDD | Single positive supply rail (4.5–16 V); powers both amplifiers and shutdown circuitry from one node. |
| 9 | Amplifier 1 output | Full-swing output capable of driving 50 mA loads down to 0.5 V above GND and up to VDD−1.5 V. |
| 10 | Amplifier 2 shutdown | Independent enable/disable control for second amplifier; identical timing (ton = 0.47 μs, toff = 2.5 μs at 12 V). |
| 11 | No connect | Internally unconnected; no external connection required or recommended. |
| 12 | No connect | Internally unconnected; floating pin has no electrical function. |
| 13 | Amplifier 1 shutdown | Redundant labeling for Pin 1 per TI's standard DIP-14 pinout convention for dual op-amps with shutdown. |
| 14 | Amplifier 2 output | Same output drive and noise specs as Pin 9; allows independent dual-channel signal processing in compact layout. |
Key Features
| Feature | Design Value |
|---|---|
| BiMOS LBC3 process | Combines CMOS input stage (≤100 pA IIB) with bipolar output (±57 mA IO), eliminating trade-off between input impedance and output drive. |
| Independent dual shutdown | Each amplifier disables separately via dedicated SHDN pins (1 & 10), enabling dynamic power gating in multi-stage analog signal paths. |
| Wide supply range | Operates from 4.5 V to 16 V single supply - supports direct integration into 5 V, 12 V, and mixed-voltage industrial systems without level-shifting. |
| Low THD+N | 0.005% at 1 kHz, 8 VPP, RL = 10 kΩ - preserves fidelity in audio line drivers and DAC output buffers. |
| High PSRR & CMRR | 100 dB PSRR and 95 dB CMRR (typ.) - rejects supply ripple and common-mode interference in noisy automotive or factory-floor environments. |
| Stable with capacitive loads | Maintains ≥32° phase margin with 50 pF load - eliminates need for isolation resistors in ADC driver or cable-driving applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL072CP | Lower bandwidth (3 MHz), higher input offset (3 mV max), no shutdown, 2.5 mA/ch supply current. | Lacks shutdown control and high-output drive; unsuitable for power-sensitive or heavy-load applications. | Select TLC073CN when >3× bandwidth, <5% offset, or ±57 mA drive is required; TL072CP only where cost is primary and performance margins are ample. |
| TLC27L2CN | CMOS-only, 1.7 MHz GBW, 0.025 mA/ch supply current, 10 mV VIO max, no shutdown. | Ultra-low power but insufficient speed/noise performance for audio or fast sensor interfaces. | Choose TLC073CN over TLC27L2CN when signal integrity, speed, or drive strength outweigh ultra-low-power needs. |
Compared with TL072CP and TLC27L2CN, the TLC073CN delivers 3.3× higher bandwidth, 50× lower input offset voltage, and integrated shutdown-making it the only option among the three that simultaneously satisfies high-fidelity audio, industrial sensor, and automotive EMI-resilient design requirements.

FAQ
What is the operating temperature range of the TLC073CN?
The TLC073CN is rated for operation from −40°C to 125°C, meeting industrial and automotive under-hood requirements. This extended range is confirmed in the "recommended operating conditions" table of the SLOS219F datasheet, where the "I-suffix" designation applies to the CN package variant, ensuring reliability across harsh thermal environments without derating.
Does the TLC073CN support true rail-to-rail output swing?
The TLC073CN does not provide rail-to-rail output swing. Its output can source up to VDD − 1.5 V and sink down to 0.5 V above GND under 57 mA load, as specified in the "Electrical Characteristics" tables for VOH and VOL. This limited swing is sufficient for line-driving and sensor interface applications but requires headroom consideration in low-voltage designs.
How does the shutdown feature work on the TLC073CN?
The TLC073CN provides independent shutdown control for each amplifier via pins 1 (CH1) and 10 (CH2). When SHDN voltage is ≤0.8 V, supply current drops to 125 μA per channel; when ≥2 V, the amplifier operates normally. Turn-on time is 0.47 μs and turn-off time is 2.5 μs at VDD = 12 V, enabling rapid power cycling in responsive systems.
Can the TLC073CN drive a 600 Ω load at 5 V supply?
Yes, the TLC073CN can drive a 600 Ω load at 5 V supply. With ±57 mA output current capability, it delivers ±3.4 V output swing into 600 Ω (per VOH/VOL specs at 35 mA), supporting professional audio line-level standards (e.g., +4 dBu ≈ 1.23 VRMS). The device remains stable without external compensation due to its ≥32° phase margin with 50 pF load.
What is the input bias current specification for the TLC073CN?
The TLC073CN exhibits an input bias current of ≤100 pA (typical) over the full temperature range, as documented in the "Electrical Characteristics" section for TLC07XC variants. This ultralow value stems from its CMOS input stage and enables high-impedance sensor interfacing (e.g., pH electrodes, piezoelectric elements) without significant DC error or leakage-induced drift.
