Product details
Overview
TLC072CP from Texas Instruments is a dual-channel, wide-bandwidth (10 MHz), high-output-drive (±55 mA) single-supply operational amplifier in an 8-pin PDIP package, featuring 16 V/μs slew rate, 7 nV/√Hz input voltage noise, and 1.9 mA per channel supply current - used in audio line drivers, industrial sensor signal conditioning, and active filter stages.
For engineers reviewing the TLC072CP datasheet, TLC072CP pinout, TLC072CP application, or TLC072CP equivalent, this page delivers verified electrical parameters, validated dual-opamp circuit role, exact PDIP-8 package mapping, real-world application context, and two confirmed alternative parts with documented functional and packaging differences.
Technical Context
The TLC072CP implements a BiMOS architecture combining a CMOS front end for ultralow input bias current (≤100 pA) and high input impedance (>1 TΩ) with a bipolar output stage enabling ±55 mA drive into low-impedance loads. It operates from 4.5 V to 16 V single supply with rail-to-rail input common-mode range (0.5 V to VDD−0.8 V).
No shutdown functionality is integrated in the TLC072CP variant - unlike TLC070/TLC073 - as confirmed by absence of SHDN pin in its pinout and omission from the family's shutdown-enabled device table. Its dual-channel configuration shares power and ground pins, requiring careful thermal layout in high-current applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz gain-bandwidth product - supports stable unity-gain buffer or 10× inverting amplifier up to 1 MHz without phase margin collapse. |
| Slew Rate | +16 V/μs / −19 V/μs - enables clean 10 VPP output at ≥100 kHz in fast-settling active filters or pulse amplifiers. |
| Output Drive | IOH = 57 mA at VDD−1.5 V; IOL = 55 mA at 0.5 V - drives 600 Ω audio loads or multiple logic inputs directly without external buffers. |
| Input Noise | 7 nV/√Hz at 1 kHz - suitable for low-level sensor amplification (e.g., thermocouple, strain gauge) where noise dominates SNR. |
| Supply Range | 4.5 V to 16 V single supply - compatible with 5 V microcontroller systems and 12 V industrial rails without level-shifting. |
| Input Offset | 60 μV typical (390 μV max) - reduces DC error in precision gain stages and eliminates need for manual nulling in many designs. |
| Supply Current | 1.9 mA per channel - enables dual-amplifier operation in battery-powered instrumentation with <4 mA total quiescent draw. |
Pinout & Package
Package: 8-pin Plastic Dual Inline Package (PDIP), 0.3 inch body width, through-hole mounting, RoHS-compliant lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - capable of sourcing/sinking ±55 mA; requires local 0.1 μF bypass cap near VDD pin. |
| 2 | IN− A | Inverting input for Channel A - high-impedance CMOS node; sensitive to PCB leakage and EMI coupling. |
| 3 | IN+ A | Non-inverting input for Channel A - common-mode range extends to within 0.5 V of GND and VDD−0.8 V. |
| 4 | GND | Analog ground reference - must be star-connected to system ground; shared return for both channels. |
| 5 | IN+ B | Non-inverting input for Channel B - electrically isolated from Channel A but shares same supply and ground paths. |
| 6 | IN− B | Inverting input for Channel B - matched offset and bias performance to Channel A per datasheet matching specs. |
| 7 | OUT B | Amplifier B output - identical drive capability to OUT A; independent loading does not affect Channel A performance. |
| 8 | VDD | Positive supply rail - accepts 4.5–16 V; requires 0.1 μF ceramic + 10 μF tantalum bulk decoupling at entry point. |
Key Features
| Feature | Design Value |
|---|---|
| BiMOS process technology | Combines CMOS input stage (1000 GΩ differential resistance, ≤100 pA bias current) with bipolar output (±55 mA drive), eliminating trade-off between input precision and output strength. |
| Rail-to-rail input common-mode range | Operates with inputs from 0.5 V above GND to 0.8 V below VDD - enables direct interfacing with ADC references, DAC outputs, and single-supply sensors. |
| Low 1/f noise corner | 12 nV/√Hz at 100 Hz - maintains signal integrity in DC-coupled medical or seismic amplifiers where low-frequency noise dominates. |
| High PSRR & CMRR | 100 dB PSRR and 95 dB CMRR at 25°C - rejects power rail ripple and common-mode interference in noisy industrial environments. |
| Stable with capacitive loads | Maintains ≥32° phase margin with up to 50 pF load capacitance - simplifies design of buffered DAC outputs or long-cable drivers without isolation resistors. |
Applications
| Audio Line Driver | Industrial Sensor Signal Conditioning |

IC Role / Device Role / Timing Role: Two TLC072CP devices providing four independent gain/offset stages - each channel configured for fixed-gain instrumentation with resistor-programmed offsets. Use Value: 10 MHz GBW allows >100 kHz small-signal bandwidth for transient detection; 1.9 mA/channel keeps total system supply current under 8 mA for battery operation. |
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 noise (18 nV/√Hz), no BiMOS output stage (±10 mA drive), same PDIP-8 package and pinout. | Not suitable for high-speed or high-current applications; acceptable only where cost is primary constraint and 10 MHz BW is unnecessary. | Select TL072CP only if legacy design compatibility is required and performance margins allow 3× lower bandwidth and 2.5× higher noise. |
| OPA2340PA | Rail-to-rail input/output, lower noise (7 nV/√Hz), lower supply current (1.6 mA/ch), but reduced output drive (±20 mA) and narrower supply range (2.7–5.5 V). | Optimized for low-voltage portable systems; unsuitable for 12 V industrial rails or driving 600 Ω loads. | Choose OPA2340PA when operating from 3.3 V or battery sources and full rail-to-rail swing is mandatory - not for 5–16 V or high-current use cases. |
Compared with TL072CP, TLC072CP delivers 3.3× higher bandwidth and 2.8× stronger output drive at identical cost and footprint; versus OPA2340PA, it trades rail-to-rail output for 2.75× higher supply voltage tolerance and 2.75× greater load current capacity - making TLC072CP optimal for industrial 5–12 V signal chains demanding speed and drive.

FAQ
What is the maximum operating temperature range for the TLC072CP?
The TLC072CP is rated for commercial temperature operation from 0°C to 70°C, as indicated by the "C" suffix in the part number. It is not qualified for extended industrial (−40°C to 125°C) operation - that capability is reserved for the TLC072IP and TLC072AIP variants with "I" and "AI" suffixes.
Does the TLC072CP include a shutdown feature?
No, the TLC072CP does not include a shutdown function. Its pinout lacks a SHDN terminal, and the device is absent from TI's shutdown-enabled family members (TLC070, TLC073, TLC075). Power control must be implemented externally via supply switching or enable circuitry.
Can the TLC072CP drive a 600 Ω load at 2 VPP with minimal distortion?
Yes, the TLC072CP delivers ≤0.012% THD+N at 2 VPP into 600 Ω with AV = 10 (f = 1 kHz), per datasheet Figure 29. Its ±55 mA output current and 16 V/μs slew rate ensure linear operation without clipping or slew-induced distortion at audio frequencies.
What is the input common-mode voltage range for the TLC072CP at 5 V supply?
At VDD = 5 V, the TLC072CP supports a common-mode input range from 0.5 V to 4.2 V - extending within 0.5 V of GND and 0.8 V below VDD. This allows direct interfacing with 0–3.3 V microcontroller DACs and 0.5–4.5 V sensor outputs without level-shifting circuitry.
Is the TLC072CP pin-compatible with the TL072CP?
Yes, the TLC072CP and TL072CP share identical 8-pin PDIP packaging and pin assignments (OUT A, IN− A, IN+ A, GND, IN+ B, IN− B, OUT B, VDD), enabling drop-in replacement in existing layouts - though performance improvements (bandwidth, drive, noise) may require review of stability and transient response.
