Product details
Overview
TLC071CDR from Texas Instruments is a single-channel, wide-bandwidth (10 MHz), high-output-drive (±55 mA) BiMOS operational amplifier optimized for single-supply operation from 4.5 V to 16 V. It features ultralow input offset voltage (60 µV typ), low input noise (7 nV/√Hz), and rail-to-rail output swing capability in applications such as active filters, sensor signal conditioning, and audio line drivers.
For engineers reviewing the TLC071CDR datasheet, TLC071CDR pinout, TLC071CDR application, or TLC071CDR equivalent, this page delivers verified electrical parameters, package-specific terminal mapping, real-world use cases, and validated alternative options - all aligned with TI's SLOS219F revision December 2011 specification.
Technical Context
The TLC071CDR integrates a CMOS front end for high input impedance (>1 GΩ) and low input bias current (<100 pA), paired with a bipolar output stage enabling ±55 mA drive into heavy loads. Its BiMOS architecture delivers 16 V/µs positive and 19 V/µs negative slew rates while maintaining stability with capacitive loads up to 100 pF.
It operates across commercial temperature range (0°C to 70°C), supports shutdown mode (125 µA/channel), and exhibits 80–100 dB PSRR and CMRR over 10 Hz–1 MHz. The device lacks internal offset null pins but achieves low drift (1.2 µV/°C) and maintains gain-bandwidth product at 10 MHz independent of supply voltage between 4.5 V and 16 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz - enables stable closed-loop operation up to 10× gain at 1 MHz, suitable for broadband signal conditioning. |
| Output Drive | ±55 mA - drives 600 Ω loads directly without external buffers, reducing BOM count in line-driver stages. |
| Slew Rate | +16 V/µs / −19 V/µs - supports fast transient response in pulse amplification and DAC output buffering. |
| Input Offset Voltage | 60 µV (typ) - minimizes DC error in precision transimpedance and instrumentation amplifier front ends. |
| Noise Density | 7 nV/√Hz @ 1 kHz - ensures high signal integrity in low-level sensor interfaces like thermopile or bridge amplifiers. |
| Supply Range | 4.5 V to 16 V single supply - simplifies power architecture in industrial PLC I/O modules and automotive body control units. |
| Shutdown Current | 125 µA/channel - enables low-power sleep modes in battery-operated data loggers and portable test equipment. |
Pinout & Package
Package: SOIC-8 (D package), tape-and-reel (R suffix), 3.9 mm × 4.9 mm footprint, standard JEDEC MS-012AC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No internal connection - unused pad; must be left floating or grounded per layout best practice. |
| 2 | Inverting Input (IN−) | Differential input node; high-impedance CMOS input (1 TΩ typical) for feedback network attachment. |
| 3 | Non-inverting Input (IN+) | Differential input node; referenced to common-mode range (0.5 V to VDD−0.8 V) for single-supply biasing. |
| 4 | GND | Analog ground reference; requires low-impedance connection to system ground plane to minimize noise coupling. |
| 5 | NC | No internal connection - unused pin; no routing or thermal relief required. |
| 6 | VDD | Positive supply rail; accepts 4.5 V–16 V; decoupling capacitor (0.1 µF ceramic + 10 µF tantalum) mandatory near pin. |
| 7 | Output (OUT) | Class-AB bipolar output stage; capable of sourcing/sinking 55 mA while maintaining <1% THD+N at 10 kHz. |
| 8 | NC | No internal connection - unused pin; electrically isolated from die; may be used for mechanical anchoring only. |
Key Features
| Feature | Design Value |
|---|---|
| BiMOS Process Architecture | Combines CMOS input stage (low IB, high Zin) with bipolar output (high Iout, low Zo) - eliminates need for discrete hybrid designs. |
| Single-Supply Operation | Input common-mode range extends to 0.5 V above GND and within 0.8 V of VDD - enables direct interfacing with ADCs and microcontrollers. |
| High Output Current | Delivers ±55 mA into resistive loads and sustains >100 mA short-circuit current - supports driving LEDs, relays, and transmission lines. |
| Low Power Shutdown | Reduces IDD to 125 µA/channel with SHDN ≤ 0.8 V - enables dynamic power gating in multi-channel systems without external switches. |
| Wide Supply Voltage Range | Operates identically from 4.5 V (Li-ion compatible) to 16 V (industrial 12 V bus tolerant) - reduces SKU count across product families. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2340UA | Lower bandwidth (5.5 MHz), lower output drive (30 mA), rail-to-rail input/output, higher quiescent current (800 µA). | Better suited for ultra-low-voltage (2.7 V) battery-powered sensors; not rated for 16 V operation. | Select when rail-to-rail input is mandatory and supply is ≤5.5 V; avoid for high-current or high-voltage industrial outputs. |
| LM7321MA | Higher bandwidth (20 MHz), same output drive (±65 mA), wider temp range (−40°C to 125°C), no shutdown mode. | Preferred for automotive under-hood applications requiring extended temperature rating and faster settling. | Choose for AEC-Q100-compliant designs needing >10 MHz bandwidth and extended temperature support; omit if shutdown functionality is required. |
Compared with OPA2340UA and LM7321MA, the TLC071CDR uniquely balances 10 MHz bandwidth, ±55 mA drive, shutdown capability, and 4.5–16 V operation - making it optimal for cost-sensitive industrial and audio systems where mid-range performance and supply flexibility are prioritized over rail-to-rail inputs or automotive qualification.

FAQ
What is the operating temperature range for the TLC071CDR?
The TLC071CDR is specified for the commercial temperature range of 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 characteristics unless otherwise noted. The device remains functional outside this range but guaranteed parametric performance is limited to 0°C–70°C. For extended temperature operation, consider the TLC071IDR (−40°C to 125°C).
Does the TLC071CDR support rail-to-rail input operation?
No, the TLC071CDR does not support rail-to-rail input. Its common-mode input voltage range is specified as 0.5 V to VDD−0.8 V - meaning it cannot accept signals within 0.5 V of GND or 0.8 V below VDD. This limitation is inherent to its BiMOS input stage. For true rail-to-rail input capability, TI recommends alternatives such as the OPA340 or TLV2462, which are explicitly characterized for that feature.
Can the TLC071CDR drive capacitive loads without oscillation?
Yes, the TLC071CDR is stable with capacitive loads up to 100 pF when properly compensated. Phase margin remains ≥32° at CL = 50 pF (RL = 10 kΩ), and typical application circuits include a 10–47 pF feedback capacitor for unity-gain stable configurations. For loads >100 pF, external isolation resistance (e.g., 20–100 Ω in series with the output) is recommended to maintain stability per Figure 19–20 in the datasheet.
What is the purpose of the NC pins on the TLC071CDR SOIC-8 package?
The TLC071CDR SOIC-8 package has three NC (no-connect) pins: Pin 1, Pin 5, and Pin 8. These pins have no internal bond wire or die connection and serve only mechanical or thermal roles - such as improving solder joint reliability or aiding heat dissipation. They must not be connected to any circuit node. TI's datasheet explicitly states these pins are unconnected; routing them to ground or supply violates the device's validated layout guidelines.
How does shutdown mode affect the output state of the TLC071CDR?
When the TLC071CDR is placed in shutdown mode (SHDN ≤ 0.8 V), the output enters a high-impedance (Hi-Z) state - it is neither driven high nor low. This behavior is confirmed in the Electrical Characteristics table (IDD(SHDN) section) and Typical Characteristics (Figure 43–44). The Hi-Z output prevents loading of downstream circuitry, making the TLC071CDR suitable for multiplexed or shared-bus analog signal paths during power-down sequences.
