Product details
Overview
TLV272CD from Texas Instruments is a dual rail-to-rail output operational amplifier optimized for low-power, wide-bandwidth signal conditioning in battery-powered and industrial systems. It delivers 3-MHz gain-bandwidth, 2.4 V/µs slew rate, 550 µA per channel supply current, and 39 nV/√Hz input voltage noise across a 2.7 V to 16 V supply range - enabling precision sensing and analog front-end design in smoke detectors and solar inverters.
For engineers reviewing the TLV272CD datasheet, TLV272CD pinout, TLV272CD application, or TLV272CD equivalent, key selection considerations include its rail-to-rail output swing at low supply voltages (down to 2.7 V), ultra-low 1 pA input bias current for high-impedance sensor interfaces, and guaranteed operation over –40°C to +125°C industrial temperature range.
Technical Context
The TLV272CD uses CMOS input stage architecture to achieve 1 pA input bias current and rail-to-rail output swing via complementary push-pull output transistors. Its 3-MHz unity-gain bandwidth is maintained across 2.7–16 V supply, with phase margin ≥65° into 10 pF load - supporting stable closed-loop configurations without external compensation in most filter and buffer applications.
It operates in single-supply mode (2.7–16 V) or split-supply mode (±1.35 V to ±8 V), with common-mode input range extending from GND to VDD −1.35 V. Input offset voltage is specified at 5 mV (typical) and 7 mV (max) over full temperature range, and PSRR is 70–80 dB across supply variations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 16 V - supports Li-ion (3.0–4.2 V), 5 V microcontroller rails, and ±5 V legacy systems without level-shifting. |
| Gain-Bandwidth Product | 3 MHz (typical at VDD = 5 V) - enables stable unity-gain buffers and second-order filters up to ~50 kHz cutoff. |
| Slew Rate | 2.4 V/µs (typical at VDD = 5 V) - supports 1 VPP signals up to ~380 kHz without distortion in voltage-follower configuration. |
| Input Bias Current | 1 pA (typical at 25°C) - minimizes voltage error in high-Z sensor circuits (e.g., photodiode, thermistor, pH electrode). |
| Input Noise Voltage | 39 nV/√Hz (at 1 kHz) - suitable for low-level signal amplification where thermal noise dominates above ~100 Hz. |
| Rail-to-Rail Output | Swings within 135 mV of each rail at 1 mA load - maximizes dynamic range in 3.3 V or lower single-supply systems. |
| Quiescent Current | 550 µA per channel - enables dual-opamp functionality in micropower designs (e.g., battery-powered building automation nodes). |
Pinout & Package
TLV272CD is packaged in an 8-pin SOIC (D package) with 4.98 mm × 3.91 mm body size and standard 1.27 mm pitch. The package is RoHS-compliant, surface-mountable, and rated for industrial temperature operation (–40°C to +125°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Output, Channel 1 | Amplified output node for first opamp; capable of sourcing/sinking ≥4 mA while maintaining rail-to-rail swing. |
| 2OUT | Output, Channel 2 | Amplified output node for second opamp; electrically isolated from 1OUT but shares same VDD/GND rails. |
| 1IN− | Inverting Input, Ch. 1 | Differential input terminal for channel 1; high-impedance CMOS node (1 pA bias) for precision feedback networks. |
| 1IN+ | Noninverting Input, Ch. 1 | Differential input terminal for channel 1; matched to 1IN− for minimal input offset voltage drift. |
| 2IN− | Inverting Input, Ch. 2 | Differential input terminal for channel 2; independent of channel 1 inputs - no crosstalk specification provided. |
| 2IN+ | Noninverting Input, Ch. 2 | Differential input terminal for channel 2; fully decoupled from channel 1 for dual-channel signal processing. |
| GND | Negative Supply / Ground | Reference node for single-supply operation; must be low-impedance return path for both channels' output currents. |
| VDD | Positive Supply | Power rail for both opamps; accepts 2.7–16 V DC; requires local 0.1 µF ceramic bypass capacitor near pin. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Enables full-scale utilization of 3.3 V or lower ADC reference voltages without level-shifting circuitry. |
| 3-MHz bandwidth at 550 µA | Delivers >10× higher speed-per-power than TLC272, allowing faster response in motor control feedback loops. |

| –40°C to +125°C operation | Qualified for under-hood automotive and outdoor solar inverter environments without derating. |
| CMOS input stage | Provides high input impedance (>1 TΩ) and low input capacitance (8 pF), minimizing loading on high-Q resonant sensors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV272IDR | Same electrical specs; VSSOP-8 (3.0 mm × 3.0 mm) package instead of SOIC-8; identical –40°C to +125°C rating. | Preferred for space-constrained PCBs; requires finer pitch reflow profile; thermal resistance RθJA = 186.6°C/W vs 127.2°C/W for SOIC. | Select TLV272IDR when board area is critical and thermal management permits higher junction temperature rise. |
| TLC272CD | Lower bandwidth (1.7 MHz), higher supply current (675 µA/ch), wider input offset (1100 µV max), no rail-to-rail output (1.5 V headroom required). | Legacy drop-in for non-rail-to-rail designs; unsuitable for 3.3 V systems requiring full output swing. | Choose TLC272CD only for cost-sensitive, non-battery, non-low-voltage applications where rail-to-rail is unnecessary. |
Compared with TLV272IDR, TLV272CD offers better thermal performance and easier assembly but occupies more board area; compared with TLC272CD, TLV272CD enables lower-voltage operation, higher precision, and reduced power consumption - making it the preferred upgrade for modern energy-efficient designs.

FAQ
What is the maximum operating supply voltage for TLV272CD?
The absolute maximum supply voltage for TLV272CD is 16.5 V, but the recommended operating range is 2.7 V to 16 V. Operation at 16 V is supported across the full –40°C to +125°C temperature range and enables compatibility with ±8 V split supplies or multi-cell battery stacks. Exceeding 16.5 V risks permanent damage per TI's Absolute Maximum Ratings table.
Does TLV272CD support rail-to-rail input capability?
No, TLV272CD does not feature rail-to-rail input. Its common-mode input voltage range is specified from GND to VDD −1.35 V at 25°C - meaning the inputs cannot reliably operate within 1.35 V of the positive rail. This limitation is inherent to its CMOS input stage design and must be accounted for in biasing networks, especially in single-supply configurations.
Can TLV272CD drive capacitive loads directly?
TLV272CD can drive ≤10 pF capacitive loads stably without external compensation. For loads exceeding 10 pF (e.g., long PCB traces or ADC input capacitance), Texas Instruments recommends adding a series resistor (RNULL ≥20 Ω) between the output pin and the load to maintain ≥65° phase margin and prevent oscillation - as documented in Section 8.3.3 of the SLOS351E datasheet.
What is the input offset voltage specification for TLV272CD?
TLV272CD has a maximum input offset voltage of 7 mV over the full industrial temperature range (–40°C to +125°C), with typical value of 5 mV at 25°C. This parameter is measured with VDD = 2.7 V, 5 V, or ±5 V, RL = 10 kΩ, VO = VDD/2, and RS = 50 Ω. Offset voltage drift is 2 µV/°C (typical), contributing predictably to total error in precision DC-coupled applications.
Is TLV272CD pin-compatible with other dual opamps in SOIC-8 packages?
TLV272CD follows the industry-standard dual opamp pinout (1OUT, 2IN−, 2IN+, GND, 1IN+, 1IN−, 2OUT, VDD) and is pin-compatible with TLC272CD, TLV2372IDR, and LMV358IDR in SOIC-8. However, functional differences - such as rail-to-rail output, bandwidth, and supply current - require verification of system-level performance even when footprint matches.
