Product details

Overview

TS27M2CDT from STMicroelectronics is a low-power CMOS dual operational amplifier in SO-8 package, designed for single-supply operation from 3 V to 16 V, delivering 150 µA/op typical supply current, 1 MHz gain bandwidth product, and rail-to-ground output swing - used in battery-powered sensor signal conditioning and portable medical instrumentation.

For engineers reviewing the TS27M2CDT datasheet, TS27M2CDT pinout, TS27M2CDT application, or TS27M2CDT equivalent, key selection criteria include ultra-low quiescent current, input offset voltage ≤12 mV (C-grade), common-mode input range to ground, phase margin stability with 100 pF capacitive loads, and SO-8 thermal resistance of 125 °C/W.

Technical Context

The TS27M2CDT implements a two-stage CMOS transconductance amplifier architecture with class-AB output stage, enabling rail-to-ground output swing while maintaining 45° phase margin at unity gain with 100 pF load. Its input stage uses matched p-channel MOSFETs to achieve <150 pA input bias current and <2 µV/°C offset drift.

It operates across 0°C to +70°C ambient temperature, supports single-supply configurations down to 3 V, and features 65 dB common-mode rejection and 60 dB supply voltage rejection - optimized for DC-coupled, low-frequency (<100 kHz) amplification where power efficiency and input impedance (>10¹² Ω) are critical.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	3 V to 16 V - enables direct use with Li-ion, 5 V, and 12 V rails without regulation
Quiescent Current	150 µA per amplifier - allows >1-year battery life in coin-cell–powered devices
Gain Bandwidth Product	1 MHz typ - supports stable closed-loop gain up to 100 at 10 kHz
Input Offset Voltage	≤12 mV max (C grade) - ensures ≤120 µV error in 10× gain sensor interfaces
Output Swing	Rail-to-ground (V_OL = 50 mV @ I_L = 1 mA) - preserves dynamic range in single-supply ADC front-ends
Phase Margin	45° min @ unity gain, 100 pF load - guarantees stability without external compensation
Common-Mode Range	0 V to V_CC − 1.5 V - accepts inputs down to ground in single-supply configurations

Pinout & Package

TS27M2CDT is housed in an SO-8 (Small Outline) plastic micropackage with standard 1.27 mm pitch, 5.0 mm × 6.2 mm body, and 125 °C/W junction-to-ambient thermal resistance.

Pin/Terminal	Circuit Role	Design Meaning
1	Inverting Input (Amplifier 1)	High-impedance node accepting differential signal reference; requires guarded trace routing
2	Non-inverting Input (Amplifier 1)	DC-biased input for single-supply operation; connects to sensor mid-rail or ground-referenced source
3	Output (Amplifier 1)	Class-AB buffered output capable of sinking 34 mA and sourcing 45 mA into resistive loads
4	V_CC− (Ground)	Power return for both amplifiers; must be low-inductance connection to PCB ground plane
5	Inverting Input (Amplifier 2)	Independent second channel input; electrically isolated from Channel 1 except via shared supply pins
6	Non-inverting Input (Amplifier 2)	Enables dual-sensor monitoring or differential pair configuration without cross-talk
7	Output (Amplifier 2)	Matches Channel 1 performance; supports independent gain/feedback networks
8	V_CC+ (Supply)	Single positive supply input; decoupling capacitor (100 nF) required within 5 mm

Key Features

Feature	Design Value
Ultra-low power consumption	150 µA/op enables always-on operation in energy-harvesting nodes and wearable biosensors
Rail-to-ground output swing	Eliminates need for negative supply or level-shifting circuitry in single-rail systems
Stable with capacitive loads	45° phase margin at 100 pF allows direct driving of ADC input capacitance or long cables
High input impedance	>10¹² Ω minimizes loading on high-Z sources like piezoelectric sensors and pH electrodes
Low input current drift	2 µV/°C offset drift ensures <±0.2 mV error over 0–70°C industrial temperature range

Equivalent & Alternatives

The following parts are listed as comparable options for similar low-power dual op-amp applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
LMV358IDR	Higher supply current (80 µA/op vs. 150 µA/op), lower GBP (1 MHz vs. same), wider temp range (−40°C to +125°C)	Preferred in automotive cabin modules requiring extended temperature rating	Select if extended temperature range outweighs 30% higher quiescent current
TLV2462CDR	Lower input offset (2 mV max), higher drive strength (60 mA short-circuit), but 2× higher ICC (300 µA/op)	Suitable for precision analog outputs requiring tighter DC accuracy and higher load current	Choose when offset voltage <2 mV is mandatory and power budget permits doubling ICC

Compared with LMV358IDR and TLV2462CDR, TS27M2CDT offers the lowest ICC among SO-8 dual CMOS op-amps rated for 0–70°C, making it optimal for cost-sensitive, battery-limited applications where 12 mV offset and 1 MHz GBP meet system requirements.

FAQ

What is the maximum capacitive load the TS27M2CDT can drive while remaining stable?

The TS27M2CDT maintains ≥45° phase margin with up to 100 pF capacitive load at unity gain, as verified in Figure 11 of the datasheet. For loads exceeding 100 pF, a small series resistor (10–47 Ω) between output and load is recommended to isolate capacitance and preserve stability without degrading bandwidth significantly.

Does the TS27M2CDT support true rail-to-rail input?

No - its common-mode input voltage range is specified as 0 V to V_CC − 1.5 V, meaning the input cannot accept signals within 1.5 V of the positive rail. However, it does support rail-to-ground output swing, allowing full utilization of the lower portion of the supply range in single-supply configurations.

Can TS27M2CDT operate from a 3.3 V supply?

Yes - the device is fully specified from 3 V to 16 V. At 3.3 V, typical supply current remains ~150 µA/op, GBP drops to ~0.5 MHz (per Figure 9), and output swing is reduced to ~2.5 V (V_OH) and ~50 mV (V_OL), supporting 10-bit ADC interfacing with appropriate gain staging.

Is the TS27M2CDT RoHS-compliant and halogen-free?

Yes - the TS27M2CDT is manufactured in ST's ECOPACK®-compliant SO-8 package, meeting RoHS Directive 2011/65/EU and halogen-free requirements per IEC 61249-2-21, with lead finish conforming to JEDEC J-STD-020 moisture sensitivity level 3.
