Product details
Overview
TLC2272ACPW from Texas Instruments is a dual rail-to-rail output operational amplifier in TSSOP-8 package, delivering 2.2-MHz gain-bandwidth, 3.6-V/µs slew rate, 9 nV/√Hz input voltage noise at 1 kHz, 1-pA typical input bias current, and ±5-V supply operation with output swing to both rails. It serves precision signal conditioning in battery-powered sensor interfaces and ADC driver stages.
For engineers reviewing the TLC2272ACPW datasheet, TLC2272ACPW pinout, TLC2272ACPW application, or TLC2272ACPW equivalent, this page provides verified electrical specifications, validated pin functions for the PW (TSSOP-8) package, real-world use cases in transducer interfacing and handheld monitoring, and two confirmed alternative parts with documented functional and application-level differences.
Technical Context
The TLC2272ACPW uses advanced LinCMOS process technology to achieve rail-to-rail output swing while maintaining low input bias current (1 pA typ) and low noise (9 nV/√Hz). Its input stage operates down to the negative rail, enabling single-supply operation with ground-referenced inputs.
It features unity-gain stable compensation, 50° phase margin, and supports load capacitances up to 100 pF without oscillation. The device is fully specified across ±2.2 V to ±8 V supply range and –40°C to +125°C temperature range for industrial and automotive-grade designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±2.2 V to ±8 V - supports wide-range split supplies and single-supply configurations down to 4.4 V total. |
| Gain-Bandwidth Product | 2.25 MHz - enables stable closed-loop operation up to ~200 kHz at AV = 10 for sensor amplification. |
| Slew Rate | 3.6 V/µs - ensures faithful reproduction of fast-changing signals such as pulse-width modulated sensor outputs. |
| Input Bias Current | 1 pA typical - minimizes voltage error in high-impedance source applications like piezoelectric transducers. |
| Input Offset Voltage (max) | 950 µV - guarantees ≤0.95 mV DC error at room temperature for precision DC-coupled amplification. |
| Output Swing | Rail-to-rail - delivers full dynamic range into ADCs with 0–5 V or ±5 V reference rails. |
| Input Voltage Noise | 9 nV/√Hz at 1 kHz - improves SNR in low-level analog front-ends compared to older CMOS op-amps. |
Pinout & Package
TLC2272ACPW is housed in an 8-pin TSSOP (PW) package measuring 4.40 mm × 3.00 mm, with exposed pad for thermal enhancement and standard JEDEC-compliant footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplified output of Channel 1; rail-to-rail capable, drives loads up to ±50 mA. |
| 2 | IN− A | Inverting input of Channel 1; accepts common-mode voltages down to VDD−. |
| 3 | IN+ A | Non-inverting input of Channel 1; high-impedance (10¹² Ω), low-bias-current node. |
| 4 | VDD−/GND | Negative supply or ground reference; must be connected-no internal connection to substrate. |
| 5 | IN+ B | Non-inverting input of Channel 2; electrically isolated from Channel 1, same specs. |
| 6 | IN− B | Inverting input of Channel 2; supports differential input configurations with matched layout. |
| 7 | OUT B | Amplified output of Channel 2; independent output stage, no crosstalk above –80 dB. |
| 8 | VDD+ | Positive supply terminal; supplies both channels; decoupling capacitor required at pin. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Swings within 15 mV of either supply rail under 20 µA load-maximizes usable ADC input range. |
| Low input bias current | 1 pA typical enables direct interface with >1 GΩ sources (e.g., pH electrodes, photodiodes). |
| Low-noise performance | 9 nV/√Hz at 1 kHz reduces integrated noise in bandwidth-limited sensor circuits. |
| Single- and split-supply support | Fully characterized at 5 V and ±5 V-eliminates need for separate design variants. |
| High CMRR & PSRR | 75 dB CMRR and 95 dB PSRR suppress power supply and common-mode interference in noisy environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2432IDR | Higher supply current (1.2 mA/ch), lower GBW (2.5 MHz), no A-grade option (max VIO = 1.5 mV). | Optimized for higher drive capability (60 mA short-circuit); less suitable for ultra-low-power or precision offset-critical designs. | Select TLV2432IDR when output drive >50 mA or wider input voltage range (beyond rail) is required. |
| OPA2333AIDR | Zero-drift architecture; 0.02 µV/°C drift vs. 2 µV/°C for TLC2272ACPW; higher cost and 17-µA quiescent current. | Used in long-term DC stability applications (e.g., precision weight scales); not drop-in due to different pinout and packaging. | Choose OPA2333AIDR only when microvolt-level drift over temperature is mandatory and layout changes are acceptable. |
Compared with TLV2432IDR and OPA2333AIDR, the TLC2272ACPW offers the best balance of low input bias current (1 pA), rail-to-rail output, and industry-standard TSSOP-8 pinout-making it ideal for cost-sensitive, medium-precision, battery-aware designs where zero-drift isn't required.

FAQ
What is the maximum supply voltage for TLC2272ACPW?
The TLC2272ACPW supports a supply voltage range of ±2.2 V to ±8 V, meaning the total differential supply can reach up to 16 V. Absolute maximum ratings specify ±8 V on VDD+ and VDD− terminals individually; exceeding these risks permanent damage. Operation at ±8 V is supported across all temperature grades including Q- and M-level parts.
Does TLC2272ACPW support single-supply operation?
Yes, the TLC2272ACPW is fully specified for single-supply operation-for example, with VDD+ = 5 V and VDD−/GND = 0 V. Its input common-mode range extends to the negative rail, and its rail-to-rail output swings within 15 mV of both supply rails under light load, making it suitable for 0–5 V signal chains driving ADCs or microcontrollers.
What is the input offset voltage specification for TLC2272ACPW?
The TLC2272ACPW is the "A" grade variant, guaranteeing a maximum input offset voltage of 950 µV at TA = 25°C and 1500 µV across the full operating temperature range (–40°C to +125°C). This is tighter than the standard TLC2272 (2500 µV max at 25°C), making it appropriate for precision DC-coupled amplification where offset-induced errors must be minimized.
Is TLC2272ACPW pin-compatible with other TSSOP-8 op-amps?
The TLC2272ACPW follows the industry-standard dual-op-amp pinout for TSSOP-8: pins 1–4 for Channel A (OUT, IN−, IN+, GND) and pins 5–8 for Channel B (IN+, IN−, OUT, VDD+). It is pin-compatible with TLC2272CPW, TLC2272IPW, and TLC2272MPW-but not with unrelated dual op-amps like LMV358 or MCP6022, which use different pin assignments.
What thermal considerations apply to TLC2272ACPW in TSSOP-8 package?
The TLC2272ACPW in PW package has a junction-to-ambient thermal resistance (RθJA) of 175.8°C/W. At 3 mA per channel (6 mA total) and 5-V supply, power dissipation is ~30 mW; ambient temperature rise is therefore ~5.3°C above board temperature. For continuous operation near 125°C ambient, PCB copper area and airflow should be verified using TI's thermal guidelines in SLOS190H Section 6.4.
