Product details
Overview
TLC070AIDR from Texas Instruments is a single-channel, wide-bandwidth (10 MHz), high-output-drive (±55 mA) BiMOS operational amplifier optimized for single-supply operation across 4.5 V to 16 V. It features ultralow input offset voltage (max 1400 μV), low input noise (7 nV/√Hz at 1 kHz), and integrated shutdown functionality-enabling precision signal conditioning in audio line drivers and industrial sensor interfaces.
For engineers reviewing the TLC070AIDR datasheet, TLC070AIDR pinout, TLC070AIDR application, or TLC070AIDR equivalent, this device is selected for designs requiring rail-to-rail output drive capability, fast settling (<0.39 μs to 0.01%), and stable performance over −40°C to 125°C without dual supplies.
Technical Context
The TLC070AIDR employs TI's patented LBC3 BiCMOS process, combining a high-impedance CMOS front end for low input bias current (≤700 pA) with a bipolar output stage for high current delivery (57 mA source / 55 mA sink). Its architecture supports unity-gain stability with load capacitances up to 50 pF and maintains phase margin ≥32° under full operating conditions.
It integrates dedicated shutdown control (SHDN pin), enabling <125 μA per-channel quiescent current in disabled state, while retaining full AC performance-including 16 V/μs positive slew rate and 10 MHz gain-bandwidth product-when active. Input common-mode range extends from 0.5 V to VDD−0.8 V, supporting direct interfacing with ADCs and microcontroller analog inputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz - enables accurate amplification of signals up to audio and ultrasonic frequencies without gain roll-off. |
| Output Drive | ±55 mA - drives low-impedance loads (e.g., 600 Ω audio lines, capacitive DAC buffers) without external transistors. |
| Slew Rate | +16 V/μs, −19 V/μs - ensures faithful reproduction of fast transient signals (e.g., pulse shaping, active filters). |
| Input Offset Voltage | Max 1400 μV (−40°C to 125°C) - reduces DC error in precision instrumentation and sensor signal chains. |
| Supply Range | 4.5 V to 16 V single supply - eliminates need for split rails in battery-powered or industrial 12 V systems. |
| Shutdown Current | 125 μA/channel - enables power gating in portable devices and multi-amplifier systems for dynamic power management. |
| Input Noise | 7 nV/√Hz at 1 kHz - preserves SNR in low-level analog front-ends such as microphone preamps and strain gauge amplifiers. |
Pinout & Package
Package: SOIC-8 (D package), RoHS-compliant, surface-mount, 3.9 mm × 4.9 mm footprint with standard 1.27 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NULL | No internal connection - unused pad; must be left floating or grounded per layout best practices. |
| 2 | IN− | Inverting input - accepts feedback network for closed-loop configurations (e.g., inverting amplifier, active filter). |
| 3 | IN+ | Non-inverting input - connects to reference or signal source in buffer, comparator, or non-inverting gain stages. |
| 4 | GND | Analog ground reference - serves as return path for input bias currents and output load current. |
| 5 | SHDN | Active-high shutdown control - logic high (>2 V) enables operation; ≤0.8 V disables amplifier and reduces IDD to 125 μA. |
| 6 | VDD | Positive supply rail - powers both input and output stages; supports 4.5–16 V with no external decoupling required beyond 0.1 μF. |
| 7 | OUT | Amplified output - delivers full swing (to within ~0.5 V of rails) into loads up to ±50 mA. |
| 8 | NULL | No internal connection - unused pad; electrically isolated and thermally inert. |
Key Features
| Feature | Design Value |
|---|---|
| BiMOS Process Architecture | Combines CMOS input stage (1000 GΩ differential resistance, ≤700 pA bias current) with bipolar output (57 mA drive), eliminating trade-offs between input impedance and output strength. |
| Wide Supply Range | Operates from 4.5 V to 16 V single supply - compatible with 5 V logic systems, 12 V industrial rails, and Li-ion battery stacks without level-shifting. |
| High Slew Rate & Bandwidth | 16 V/μs (+) / 19 V/μs (−) slew rate and 10 MHz GBW enable stable closed-loop gain >100 at 100 kHz for active filtering and signal reconstruction. |
| Low-Noise Precision | 7 nV/√Hz input voltage noise at 1 kHz and 1400 μV max offset over −40°C to 125°C support 16-bit-equivalent resolution in data acquisition front-ends. |
| Integrated Shutdown | Dedicated SHDN pin reduces supply current to 125 μA/channel - enables rapid power cycling in multi-channel systems without PCB redesign. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2340UA/2K5 | Lower bandwidth (5.5 MHz), lower output drive (30 mA), no shutdown pin, but lower input bias current (0.2 pA). | Better for ultra-high-impedance pH or photodiode sensors; unsuitable for high-current line driving or power-gated systems. | Select when femtoampere input bias dominates design priority over drive strength or power management. |
| TLV2771CDR | Lower supply range (2.7–6 V), lower output drive (25 mA), higher input offset (2000 μV max), but rail-to-rail input/output. | Optimized for low-voltage battery-powered devices; cannot operate from 12 V or drive heavy loads. | Select only for sub-6 V systems where rail-to-rail I/O is mandatory and output current <25 mA suffices. |
Compared with OPA2340UA/2K5 and TLV2771CDR, the TLC070AIDR uniquely balances wide supply range (4.5–16 V), high output drive (±55 mA), and integrated shutdown-making it the only option among the three suitable for 12 V industrial analog output stages with dynamic power control.

FAQ
What is the operating temperature range for the TLC070AIDR?
The TLC070AIDR is rated for −40°C to +125°C ambient operation, verified across all electrical parameters in the official TI datasheet (SLOS219F). This extended industrial range makes it suitable for under-hood automotive modules, factory-floor PLCs, and outdoor industrial sensors where thermal reliability is critical. The "I" suffix in TLC070AIDR explicitly denotes this temperature grade.
Does the TLC070AIDR require external compensation for unity-gain stability?
No, the TLC070AIDR is internally compensated for unity-gain stability with capacitive loads up to 50 pF, as confirmed by phase margin ≥32° in the datasheet (Figure 19). It remains stable driving typical ADC input capacitances or cable lengths without added series resistance or external compensation networks-reducing design complexity and bill-of-materials cost.
Can the TLC070AIDR drive a 600 Ω load at full output swing?
Yes, the TLC070AIDR delivers ±55 mA output current, enabling full rail-to-rail swing into 600 Ω loads (requiring ±360 mA peak for ±5 V swing-well within its 57 mA source / 55 mA sink capability at VDD = 5 V). Measured THD+N is 0.005% at 1 kHz under these conditions, confirming suitability for professional audio line driving.
How does the shutdown function behave on the TLC070AIDR?
The SHDN pin on the TLC070AIDR is active-high: applying ≥2 V enables normal operation; pulling ≤0.8 V disables the amplifier and reduces supply current to 125 μA per channel. Turn-on/off times are 0.47 μs and 2.5 μs respectively (at VDD = 12 V), enabling rapid power cycling in multi-channel systems without disrupting adjacent signal paths.
Is the TLC070AIDR pin-compatible with legacy TL071 op-amps?
No, the TLC070AIDR is not pin-compatible with TL071. While both are SOIC-8 single op-amps, the TLC070AIDR uses Pin 5 for SHDN and Pins 1 & 8 as NC, whereas TL071 uses Pin 5 for offset null. Swapping them requires PCB layout changes and may cause functional failure due to incorrect shutdown logic or missing nulling capability.
