Product details

Overview

TLC073CD 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 TLC073CD datasheet, TLC073CD pinout, TLC073CD application, or TLC073CD 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 TLC073CD implements a BiMOS architecture-CMOS front end for ultra-high input impedance (>1 TΩ) and low input bias current (<100 pA), paired with a bipolar output stage enabling ±55 mA drive into heavy loads. Its internal shutdown logic responds to SHDN pin voltage thresholds (VIH ≥ 2 V, VOL ≤ 0.8 V) to reduce supply current from 1.9 mA/channel to 125 μA/channel.

Designed for single-supply operation across 0°C to 70°C, it supports common-mode input range from 0.5 V to VDD−0.8 V and delivers stable unity-gain performance up to 10 MHz with phase margin ≥32° (CL = 50 pF). Gain-bandwidth product remains constant at 10 MHz across 4.5–16 V supply, confirming supply-independent AC performance.

Key Specifications

Parameter	Value and Actual Design Meaning
Bandwidth	10 MHz gain-bandwidth product ensures stable closed-loop operation up to 100 kHz at AV = 100, suitable for active filters and broadband signal paths.
Slew Rate	+16 V/μs / −19 V/μs enables clean 10-VPP output at >100 kHz without slewing distortion in fast-settling applications.
Output Drive	±55 mA continuous output current allows direct driving of 600 Ω audio loads or multiple CMOS inputs without external buffers.
Input Noise	7 nV/√Hz at 1 kHz sets low-noise floor for sensor amplification where thermal noise dominates over resistor noise.
Supply Range	4.5 V to 16 V single supply supports battery-powered (5 V/12 V) and industrial (12 V/15 V) systems without split-rail generation.
Shutdown Current	125 μA/channel in shutdown mode enables power-gating in portable devices during idle periods without compromising wake-up latency.
Input Offset Voltage	60 μV typical (max 1.4 mV) minimizes DC error in precision gain stages, reducing calibration overhead in measurement front ends.

Pinout & Package

Package: SOIC-14 (D package), 8.65 mm × 3.91 mm body, 1.27 mm pitch, surface-mount, RoHS-compliant.

Pin/Terminal	Circuit Role	Design Meaning
1	1OUT	Channel 1 output; capable of sourcing/sinking ±55 mA into resistive or capacitive loads.
2	1IN−	Inverting input for channel 1; high-impedance CMOS node (1 TΩ) with <100 pA bias current.
3	1IN+	Non-inverting input for channel 1; same high-Z characteristics as 1IN−, supports rail-to-rail common-mode range.
4	GND	Analog ground reference; must be low-impedance connection shared with system AGND for noise immunity.
5	NC	No internal connection; left unconnected per TI datasheet - not usable as feedback or bypass node.
6	1SHDN	Channel 1 shutdown control; logic-high (≥2 V) enables amplifier, logic-low (≤0.8 V) disables output and reduces IDD to 125 μA.
7	NC	No internal connection; electrically isolated - no routing or grounding required.
8	VDD	Positive supply rail; accepts 4.5–16 V; decoupling capacitor (0.1 μF ceramic) required within 5 mm of pin.
9	2OUT	Channel 2 output; identical drive capability and AC performance to 1OUT, fully independent.
10	2IN−	Inverting input for channel 2; matched offset and noise to channel 1 for dual-stage designs.
11	2IN+	Non-inverting input for channel 2; supports same VICR range and bias current as 1IN+.
12	NC	No internal connection; unused pad - no electrical function.
13	2SHDN	Channel 2 shutdown control; independent logic control enables selective channel gating without affecting channel 1.
14	NC	No internal connection; mechanical pad only - no signal or power role.

Key Features

Feature	Design Value
BiMOS process architecture	Combines CMOS input stage (1 TΩ R_in, 70 pA I_IB) with bipolar output (±55 mA I_O) for simultaneous high-Z sensing and high-current drive.
Dual independent shutdown pins	1SHDN and 2SHDN allow per-channel power gating - critical for dynamic power management in multi-stage analog signal chains.
Rail-to-rail output swing	Drives within 0.5 V of GND and within 1.5 V of VDD at full load, maximizing dynamic range in single-supply systems.
Low 1/f noise corner	12 nV/√Hz at 100 Hz enables stable DC-coupled amplification of low-frequency sensor signals (e.g., thermocouples, strain gauges).
Stable with capacitive loads	Maintains ≥32° phase margin with up to 50 pF load capacitance - eliminates need for isolation resistors in ADC driver applications.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual-channel operational amplifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TL072CD	Lower bandwidth (3 MHz), lower output drive (±10 mA), higher input noise (18 nV/√Hz), no shutdown function.	Acceptable for low-speed audio preamps or DC-coupled sensor amps where power and speed are non-critical.	Select TL072CD only when cost sensitivity outweighs need for 10 MHz BW, ±55 mA drive, or shutdown control.
OPA2350UA	Higher bandwidth (38 MHz), rail-to-rail I/O, lower noise (7 nV/√Hz), but lower output drive (±50 mA), no shutdown, higher supply current (4.9 mA/ch).	Better for high-speed data acquisition or low-voltage (2.7 V) systems; unsuitable for 12–16 V industrial rails due to 5.5 V max VDD.	Choose OPA2350UA when rail-to-rail input is mandatory and supply is ≤5.5 V; avoid for 12 V sensor interfaces or shutdown-required designs.

Compared with TL072CD, TLC073CD delivers 3.3× higher bandwidth and 5.5× greater output current, enabling faster settling and heavier loads; versus OPA2350UA, it supports wider supply range (4.5–16 V) and integrated shutdown, making it superior for industrial 12 V systems with dynamic power control needs.

FAQ

What is the operating temperature range for the TLC073CD?

The TLC073CD is rated for commercial temperature operation from 0°C to 70°C, as indicated by the "C" suffix in the part number. This range is validated per TI's SLOS219F datasheet and applies to all electrical specifications unless otherwise noted. The device is not qualified for extended industrial (−40°C to 125°C) operation - that grade uses the "I" suffix (e.g., TLC073ID). For designs requiring wider ambient tolerance, the TLC073CD must be derated or thermally managed within its specified limits.

Does the TLC073CD support rail-to-rail input operation?

No, the TLC073CD does not support rail-to-rail input. Its common-mode input voltage range is specified as 0.5 V to VDD−0.8 V at 5 V supply, and 0.5 V to VDD−0.8 V at 12 V supply - meaning it cannot accept signals within 0.5 V of GND or within 0.8 V of VDD. However, it does provide rail-to-rail output swing, delivering voltages as low as 0.5 V above GND and as high as VDD−1.5 V under full load. For true rail-to-rail input, consider alternatives like the OPA2350UA.

How much output current can the TLC073CD deliver continuously per channel?

The TLC073CD delivers ±55 mA continuous output current per channel - +57 mA sourcing capability at VDD−1.5 V and −55 mA sinking capability at 0.5 V - as confirmed in the Absolute Maximum Ratings and Electrical Characteristics tables of the SLOS219F datasheet. This rating holds across the full 0°C to 70°C temperature range and 4.5–16 V supply range. Thermal derating is required above ambient temperatures where power dissipation exceeds the SOIC-14 package's 1022 mW rating at TA ≤ 25°C.

Can both channels of the TLC073CD be shut down independently?

Yes, the TLC073CD features two dedicated shutdown pins: Pin 6 (1SHDN) controls Channel 1, and Pin 13 (2SHDN) controls Channel 2. Each pin operates independently - applying ≤0.8 V to 1SHDN disables Channel 1 while leaving Channel 2 fully operational, and vice versa. This per-channel control enables flexible power sequencing in multi-stage analog signal paths, such as disabling a gain stage while keeping a buffer active, without requiring external logic or additional ICs.

What is the typical input offset voltage for the TLC073CD?

The typical input offset voltage for the TLC073CD is 60 μV at 25°C and VDD = 5 V, as stated in the Electrical Characteristics table of the SLOS219F datasheet. The maximum guaranteed value across the full 0°C to 70°C range is 1.4 mV for the standard-grade (non-A) version. This low offset supports precision DC-coupled applications like sensor amplification and active filtering where residual DC error must remain below 100 μV to avoid calibration overhead.
