Product details
Overview
TS272CDT from STMicroelectronics is a dual CMOS operational amplifier in SO-8 package, designed for single-supply (3–16 V) or split-supply operation, featuring 3.5 MHz gain-bandwidth product, 5.5 V/µs slew rate, rail-to-ground output swing, and 1 mA per amplifier supply current. It delivers stable performance on capacitive loads and supports low-power industrial signal conditioning.
For engineers reviewing the TS272CDT datasheet, TS272CDT pinout, TS272CDT application, or TS272CDT equivalent, key selection criteria include input offset voltage (≤12 mV), phase margin (40°), common-mode rejection (65 dB), supply voltage rejection (60 dB), and output drive capability (±60 mA short-circuit current).
Technical Context
The TS272CDT uses ST's silicon-gate CMOS process to achieve high input impedance (>10¹² Ω) and ultra-low input bias current (1 pA typ.), with minimal drift over temperature (2 µV/°C offset drift). Its two-stage internal architecture enables stable unity-gain operation even with 100 pF capacitive loads.
It operates across 0°C to +70°C ambient range and supports rail-to-rail output swing down to ground-critical for single-supply sensor interfaces and analog front-ends where negative supply rails are omitted.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 3.5 MHz - sets maximum closed-loop bandwidth at unity gain; usable up to ~350 kHz at gain = 10 |
| Slew Rate | 5.5 V/µs - supports fast step response in active filters and buffer stages without distortion |
| Input Offset Voltage | 12 mV max - defines DC error floor in precision amplification; trimmed version (TS272ACDT) offers 5 mV max |
| Supply Current per Amp | 1600 µA max - balances speed and power for battery-adjacent or energy-conscious designs |
| Common-Mode Range | 0 V to VCC − 1.5 V - enables direct interfacing with 0–5 V sensors and microcontroller ADC references |
| Output Short-Circuit Current | ±60 mA - provides robust fault tolerance in driver and transimpedance configurations |
| Phase Margin | 40° - ensures stability with 10 kΩ load and 100 pF capacitance; no external compensation required |
Pinout & Package
TS272CDT is housed in an 8-pin Small Outline (SO-8) plastic micropackage, compliant with JEDEC MS-012, with 1.27 mm pitch and gull-wing leads. Package dimensions: 4.9 mm × 6.0 mm × 1.75 mm (max height).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output 1 | Amplifier A output; capable of sourcing/sinking ±45 mA while maintaining rail-to-ground swing |
| 2 | Inverting Input 1 | High-impedance node (1 pA bias); connects to feedback network in inverting configurations |
| 3 | Non-inverting Input 1 | Reference input for amplifier A; common-mode range extends to ground |
| 4 | VCC− | Negative supply rail (GND in single-supply mode); must be tied to system ground or negative rail |
| 5 | Non-inverting Input 2 | Reference input for amplifier B; electrically isolated from amp A but shares supply pins |
| 6 | Inverting Input 2 | High-impedance node for amplifier B; matched to pin 2 for dual-channel symmetry |
| 7 | Output 2 | Amplifier B output; identical drive strength and voltage swing to pin 1 |
| 8 | VCC+ | Positive supply rail (3–16 V); powers both amplifiers; decoupling recommended near this pin |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-ground output swing | Enables full dynamic range utilization in single-supply systems (e.g., 0–5 V ADC interface) |
| Stable on capacitive loads | Guaranteed 40° phase margin with 100 pF load-eliminates need for isolation resistors in sensor buffering |
| Low input bias current | 1 pA typical-preserves signal integrity in high-impedance sources (e.g., pH electrodes, photodiodes) |
| Three offset voltage grades | Standard (TS272), medium-precision (TS272A), and high-precision (TS272B) variants share same pinout and package |
| CMOS input stage | Delivers >10¹² Ω input impedance-reduces loading error in passive filter and divider networks |
Applications
| Industrial Sensor Signal Conditioning | Single-Supply Active Filters |
|---|---|
|
Use Scenario: Amplifying low-level outputs from RTDs, thermocouples, or strain gauges in PLC analog input modules. IC Role / Device Role / Timing Role: Dual op-amp configured as precision instrumentation preamp (Amp A) and reference buffer (Amp B). Use Value: Rail-to-ground output allows direct connection to 0–5 V SAR ADCs; low input bias prevents offset errors in high-Z sensor bridges. |

|
Use Scenario: Signal conditioning in handheld multimeters or portable gas analyzers powered by 2×AA cells (3 V nominal). IC Role / Device Role / Timing Role: Dual op-amp serving as transimpedance converter (Amp A) and level-shifting buffer (Amp B). Use Value: Operates down to 3 V supply; 1 mA per amp enables >100-hour runtime on alkaline cells; rail-to-ground output maximizes dynamic range. |
Use Scenario: Converting 4–20 mA loop current to 0–5 V voltage for microcontroller monitoring in HVAC controllers. IC Role / Device Role / Timing Role: Dual op-amp used as precision I-to-V converter (Amp A) and output clamp/buffer (Amp B). Use Value: Low input offset (12 mV max) limits current-sense error to <0.24% FS; output sink/source capability drives 1 kΩ load directly. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual CMOS op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL072CDR | JFET-input, higher Vio (10 mV typ), higher Ib (30 pA), no rail-to-ground output | Not suitable for true single-supply 0 V referenced signals; requires negative rail for full swing | Prefer TS272CDT when ground-referenced output or ultra-low input current is required |
| LM358DT | Bipolar input, higher Icc (700 µA/amp), lower GBP (1 MHz), rail-to-rail output not supported | Limited common-mode range (0 V to VCC − 1.5 V), but cannot swing to ground with load | Choose TS272CDT for improved input impedance, lower bias current, and guaranteed ground-swing capability |
Compared with TL072CDR and LM358DT, TS272CDT uniquely combines rail-to-ground output, sub-picoampere input bias, and 3.5 MHz bandwidth in a cost-optimized SO-8 package-making it optimal for single-supply precision analog front-ends where sensor source impedance exceeds 1 MΩ.

FAQ
Is TS272CDT suitable for single-supply operation down to 3 V?
Yes. TS272CDT is fully specified for single-supply operation from 3 V to 16 V. Its input common-mode range extends to ground, and its output swings to within 50 mV of ground under 10 kΩ load-enabling direct interfacing with 3 V microcontrollers and ADCs without level-shifting circuitry.
What is the maximum capacitive load the TS272CDT can drive without oscillation?
TS272CDT maintains 40° phase margin with up to 100 pF capacitive load when driving a 10 kΩ resistive load. For loads exceeding 100 pF, a small series resistor (10–47 Ω) between output and capacitor is recommended to preserve stability in buffer or cable-driving applications.
How does TS272CDT compare to TS272IDT in terms of temperature range?
TS272CDT is rated for 0°C to +70°C operation, while TS272IDT extends to –40°C to +125°C. Both share identical electrical specifications at 25°C, but TS272IDT guarantees performance across the full industrial temperature range-including input offset voltage (12 mV max) and supply current (1700 µA max) at extremes.
Can TS272CDT replace LM358 in existing designs without layout changes?
Pin-compatible with LM358 in SO-8 package, but TS272CDT offers superior input bias current (1 pA vs. 45 nA), higher GBP (3.5 MHz vs. 1 MHz), and true rail-to-ground output. Layout reuse is possible, though decoupling and feedback network values may require verification due to higher bandwidth and lower noise.
