Product details

Overview

TS27M2BIDT from STMicroelectronics is a low-power CMOS dual operational amplifier in SO-8 package, rated for -40°C to +125°C operation, with 150 µA/op supply current, 1 MHz gain bandwidth product, and 2 mV max input offset voltage (B-grade). It delivers rail-to-ground output swing and supports single-supply operation from 3 V to 16 V, commonly used in battery-powered sensor signal conditioning and portable instrumentation.

For engineers reviewing the TS27M2BIDT datasheet, TS27M2BIDT pinout, TS27M2BIDT application, or TS27M2BIDT equivalent, key selection criteria include input offset voltage drift (2 µV/°C), phase margin stability on capacitive loads, common-mode input range (0 to V_CC − 1.5 V), and ESD robustness (1.5 kV CDM).

Technical Context

The TS27M2BIDT implements a two-stage CMOS op-amp architecture optimized for ultra-low quiescent current without sacrificing phase margin-maintaining ≥45° at unity gain with 100 pF load. Its input stage uses silicon-gate CMOS transistors, delivering picoampere-level input bias current (1–300 pA) and negligible drift over temperature.

It features rail-to-ground output capability enabled by NMOS output transistors, supporting true single-supply operation. The device lacks internal compensation for flexibility but guarantees stable unity-gain performance with 100 kΩ || 100 pF load per manufacturer characterization.

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/op typ - allows >1-year battery life in always-on sensor nodes at 3 V
Input Offset Voltage	≤2 mV max (B grade) - ensures ≤20 mV error in 10× gain signal chains at room temperature
Gain Bandwidth Product	1 MHz typ - supports stable amplification up to ~100 kHz at gain = 10
Phase Margin	≥45° at unity gain with 100 pF load - eliminates oscillation risk driving ADC input filters
Common-Mode Input Range	0 V to V_CC − 1.5 V - accepts ground-referenced sensors without level-shifting circuitry
Output Swing	Rail-to-ground (low side), up to V_CC − 0.3 V (high side) - maximizes dynamic range in single-supply systems

Pinout & Package

TS27M2BIDT is housed in an SO-8 (Small Outline) plastic micropackage, 4.8–5.0 mm × 5.8–6.2 mm footprint, 1.25 mm height, with 1.27 mm lead pitch and gull-wing leads. RoHS-compliant and ECOPACK® certified.

Pin/Terminal	Circuit Role	Design Meaning
1	Inverting input of Amp 1	High-impedance node (1–300 pA bias); connects to feedback network in inverting configurations
2	Non-inverting input of Amp 1	Accepts sensor or reference signals; common-mode range extends to ground
3	Output of Amp 1	Capable of sinking 45 mA and sourcing 34 mA; drives 100 kΩ loads directly
4	V_CC− (Ground)	Power return for both amplifiers; must be low-impedance path to minimize noise coupling
5	Inverting input of Amp 2	Independent high-Z input; electrically isolated from Amp 1 except via shared supply pins
6	Non-inverting input of Amp 2	Supports differential sensing when paired with Amp 1; same CMRR (65–80 dB) as Amp 1
7	Output of Amp 2	Matches Amp 1 output drive strength and voltage swing characteristics
8	V_CC+	Positive supply rail (3–16 V); decoupling capacitor required within 1 cm for stability

Key Features

Feature	Design Value
Ultra-low power consumption	150 µA per amplifier enables multi-year operation from coin cells in IoT endpoints
Rail-to-ground output	Eliminates need for negative supply or level-shifting in single-supply sensor front-ends
Low input offset voltage (B grade)	≤2 mV max ensures <0.2% gain error in precision 1 V full-scale measurement paths
Stable with capacitive loads	Maintains ≥45° phase margin driving 100 pF - sufficient for anti-aliasing filter integration
High CMRR and PSRR	65–80 dB CMRR and 60–80 dB PSRR suppress noise from shared PCB power domains

Applications

Portable Gas Sensor Interface

Industrial Thermocouple Amplifier

Use Scenario: Signal conditioning for electrochemical gas sensors operating from 3.3 V coin cell with microampere-level bias currents.

IC Role / Device Role / Timing Role: Dual op-amp provides transimpedance conversion (Amp 1) and reference buffer (Amp 2) in one package.

Use Value: 150 µA/op quiescent current extends battery life beyond 2 years; rail-to-ground output captures full sensor dynamic range.

Use Scenario: Cold-junction compensation and amplification of µV-level thermocouple outputs in factory-floor temperature controllers.

IC Role / Device Role / Timing Role: First-stage low-noise amplifier (Amp 1) and second-stage gain/level-shift stage (Amp 2).

Use Value: ≤2 mV V_io limits temperature error to <0.2°C at 100°C; 80 dB PSRR rejects 50/60 Hz supply ripple.

Battery Management System (BMS) Cell Monitor

Medical ECG Front-End Stage

Use Scenario: Precision voltage monitoring of individual Li-ion cells (2.5–4.2 V) in multi-cell packs under wide ambient temperature (-40°C to +125°C).

IC Role / Device Role / Timing Role: Dual amplifier configures as differential voltage monitor (Amp 1) and reference buffer for ADC (Amp 2).

Use Value: Extended temperature rating (-40°C to +125°C) ensures reliability in automotive BMS enclosures; 2 µV/°C V_io drift minimizes calibration frequency.

Use Scenario: Low-noise, low-power amplification of 0.5–5 mV ECG signals in wearable Holter monitors powered by rechargeable Li-Po batteries.

IC Role / Device Role / Timing Role: Instrumentation amplifier core (Amp 1 + Amp 2) with gain = 100 and DC-coupled output.

Use Value: 38 nV/√Hz input noise and rail-to-ground output preserve signal integrity without AC coupling; 150 µA/op enables >7-day runtime per charge.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLV2462IDR	Higher supply current (550 µA/op), wider GBW (6.4 MHz), rail-to-rail I/O	Requires higher power budget; better for higher-frequency biosignal acquisition	Select if >100 kHz bandwidth or rail-to-rail input is mandatory; avoid if battery life is critical
LMV358IDGKR	Lower V_io (3 mV max), lower cost, but only rated to +85°C and no CDM ESD rating	Limited to commercial-temperature industrial controls; unsuitable for automotive or extended-temp deployments	Choose for cost-sensitive consumer devices where extended temperature and 1.5 kV CDM immunity are not required

Compared with TLV2462IDR and LMV358IDGKR, TS27M2BIDT uniquely balances ultra-low power (150 µA/op), extended temperature support (-40°C to +125°C), and robust 1.5 kV CDM ESD protection - making it optimal for long-life, harsh-environment analog sensing where bandwidth ≤100 kHz suffices.

FAQ

What is the maximum capacitive load the TS27M2BIDT can drive while remaining stable?

The TS27M2BIDT maintains ≥45° phase margin with up to 100 pF capacitive load at unity gain, as verified in Figure 11 of the datasheet. Driving larger loads requires external isolation resistor (≥100 Ω) between output and capacitance to prevent peaking or oscillation.

Does TS27M2BIDT support true rail-to-rail input?

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

How does the B-grade (TS27M2B) differ from standard TS27M2 in offset voltage?

The B-grade guarantees ≤2 mV maximum input offset voltage at 25°C, versus ≤12 mV for the base TS27M2C variant. This tighter specification reduces initial gain error in precision measurement circuits without requiring external trimming or calibration.

Can TS27M2BIDT operate from a 3.3 V supply in a single-ended configuration?

Yes - it functions reliably from 3 V to 16 V single supply. At 3.3 V, output swing reaches 0 V (ground) to ~3.0 V, and input common-mode range spans 0 V to 1.8 V, accommodating most 3.3 V sensor outputs and reference voltages like 1.25 V or 2.5 V.
