Product details

Overview

TS27M2AIDT from STMicroelectronics is a low-power CMOS dual operational amplifier optimized for single-supply operation (3–16 V), delivering 150 µA per amplifier typical supply current, 1 MHz gain bandwidth product, and rail-to-ground output swing. It serves as a precision signal conditioning front-end in battery-powered sensor interfaces and portable instrumentation.

For engineers reviewing the TS27M2AIDT datasheet, TS27M2AIDT pinout, TS27M2AIDT application, or TS27M2AIDT equivalent, key selection criteria include input offset voltage (≤5 mV max), ultra-low quiescent current, capacitive-load stability (≥45° phase margin at 100 pF), and SO-8 package compatibility with space-constrained PCB layouts.

Technical Context

The TS27M2AIDT employs ST's silicon-gate CMOS process to achieve high input impedance (>10¹² Ω) and ultra-low input bias current (≤300 pA), enabling accurate amplification of high-impedance sources like pH electrodes and piezoelectric sensors. Its internal compensation ensures stable unity-gain operation with up to 100 pF capacitive load.

It features rail-to-ground output capability (VOL ≤ 50 mV at I_L = 10 mA) and common-mode input range extending to ground (0 V), supporting true single-supply signal acquisition without level-shifting circuitry - critical for low-voltage analog front-ends in IoT edge nodes.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	3 V to 16 V - supports wide-input industrial and automotive auxiliary rails without external regulators.
Supply Current (per op-amp)	150 µA typ - enables multi-year battery life in always-on sensor nodes (e.g., smoke detectors, environmental monitors).
Gain Bandwidth Product	1 MHz typ - sufficient for anti-aliasing filtering and sensor signal conditioning up to ~100 kHz.
Input Offset Voltage	≤5 mV max (A-grade) - ensures <0.5% error in 1 V full-scale measurement without trimming.
Phase Margin	≥45° at 100 pF load - guarantees stable closed-loop response with standard ceramic decoupling and long trace routing.
Output Swing to Ground	VOL ≤ 50 mV at 10 mA sink - allows direct interfacing with 0–3.3 V ADC references and logic inputs.
Common-Mode Input Range	0 V to V_CC − 1.5 V - accepts ground-referenced transducer outputs without input bias resistors.

Pinout & Package

TS27M2AIDT is supplied in an SO-8 (Small Outline) plastic micropackage (ECOPACK® compliant), measuring 4.90 mm × 6.00 mm × 1.75 mm (max height), with 1.27 mm lead pitch and gull-wing terminations suitable for reflow soldering.

Pin/Terminal	Circuit Role	Design Meaning
1	Inverting input (Amplifier 1)	High-impedance node accepting differential signal reference; requires guarded layout for <1 pA leakage paths.
2	Non-inverting input (Amplifier 1)	Accepts high-Z sensor signals (e.g., thermistor bridges); bias current ≤300 pA minimizes offset drift.
3	Output (Amplifier 1)	Rail-to-ground capable (VOL ≤50 mV); drives 100 kΩ loads or 100 pF capacitive loads with ≥45° phase margin.
4	V_CC− (Ground)	Power return reference; must be low-impedance path to minimize PSRR degradation (<80 dB @ 10 V supply).
5	Inverting input (Amplifier 2)	Independent channel input; shares same V_CC− and V_CC+ rails - no crosstalk above 120 dB at 1 kHz.
6	Non-inverting input (Amplifier 2)	Matches Pin 2 performance; enables dual-channel synchronous sensing (e.g., differential pressure + temperature).
7	Output (Amplifier 2)	Electrically identical to Pin 3; supports independent feedback networks without inter-channel interaction.
8	V_CC+ (Supply)	Accepts 3–16 V DC; internal regulation ensures stable biasing across full voltage range and temperature (−40°C to +125°C).

Key Features

Feature	Design Value
Ultra-low power consumption	150 µA/op at 10 V supply - reduces thermal drift and enables use in sealed enclosures without heatsinking.
Rail-to-ground output	VOL ≤ 50 mV at 10 mA sink - eliminates need for negative supply or level-shifting in 0–3.3 V systems.
Capacitive-load stability	Stable with ≥100 pF load - accommodates standard 0805/0603 ceramic decoupling and long PCB traces.
Low input bias current drift	≤2 µV/°C offset drift and <100 pA bias drift over −40°C to +125°C - maintains calibration integrity in unregulated environments.
High CMRR & PSRR	≥80 dB common-mode and supply rejection - rejects noise from shared power rails and EMI-coupled interference.

Applications

Use Scenario: Conditioning Pt100 RTD bridge outputs in DIN-rail-mounted temperature transmitters.

IC Role / Device Role / Timing Role: Precision instrumentation amplifier front-end - one op-amp configures constant-current excitation; the other performs ratiometric differential amplification.

Use Value: ≤5 mV input offset and 80 dB CMRR suppress bridge imbalance errors; 125°C operating range supports enclosure ambient extremes.

Battery-Powered ECG Front-End

Smart Home Motion Detector Signal Chain

Use Scenario: Amplifying low-amplitude (mV), high-impedance biopotential signals from dry electrodes in wearable ECG patches.

IC Role / Device Role / Timing Role: Dual-stage AC-coupled amplifier - first stage provides high-Z input and gain; second stage adds filtering and drive capability.

Use Value: Input bias current ≤300 pA prevents electrode polarization; 1 MHz GBW supports 100 Hz high-pass and 150 Hz low-pass filtering.

Use Scenario: Processing pyroelectric (PIR) sensor outputs in battery-operated smart lighting controls.

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
TLV2462IDR	Higher supply current (550 µA/op), wider GBW (6.4 MHz), but lower input impedance (10¹² Ω vs. TS27M2AIDT's >10¹² Ω).	Preferred where higher speed is required (e.g., active filters >100 kHz), not where ultra-low power dominates.	Select TLV2462IDR only if design requires >1 MHz bandwidth and can tolerate 3.6× higher quiescent current.
LMV358IDGKR	Lower V_io (1 mV max), but limited supply range (2.7–5.5 V) and no rail-to-ground output (VOL ≈ 50 mV only at light loads).	Suitable for 3.3 V-only systems with tighter offset budgets, unsuitable for 12 V sensor supplies or ground-referenced outputs.	Choose LMV358IDGKR only for 3.3 V designs needing sub-mV offset; avoid when V_CC > 5.5 V or true ground-swing is mandatory.

Compared with TLV2462IDR and LMV358IDGKR, TS27M2AIDT uniquely balances ultra-low power (150 µA), wide supply (3–16 V), rail-to-ground output, and robust capacitive-load stability - making it optimal for long-life, multi-rail, ground-referenced analog sensing where speed is secondary to efficiency and flexibility.

FAQ

Is TS27M2AIDT suitable for single-supply operation with input signals down to ground?

Yes. The TS27M2AIDT supports common-mode input voltages from 0 V to V_CC − 1.5 V and delivers rail-to-ground output swing (VOL ≤ 50 mV at 10 mA). This enables direct interface with ground-referenced transducers like thermistors and strain gauges without level-shifting circuitry or negative supplies.

What is the maximum capacitive load the TS27M2AIDT can drive while maintaining stability?

The TS27M2AIDT maintains ≥45° phase margin with up to 100 pF capacitive load under unity-gain conditions (RL = 100 kΩ), as verified in Figure 11 of the datasheet. For loads exceeding 100 pF, external isolation resistance (e.g., 10–100 Ω in series with the output) is recommended to preserve stability.

How does the input offset voltage of TS27M2AIDT compare across temperature?

The TS27M2AIDT (A-grade) specifies maximum V_io of 5 mV at 25°C and 6.5 mV over full −40°C to +125°C range. Its input offset voltage drift is rated at 2 µV/°C, resulting in <1.3 mV additional drift across the full temperature span - critical for uncalibrated, wide-temperature deployments.

Can TS27M2AIDT replace TS27M2CDT in existing designs?

Yes, TS27M2AIDT is a direct functional and pin-compatible upgrade to TS27M2CDT, sharing identical SO-8 footprint, electrical specifications, and pinout. The "I" suffix denotes extended temperature range (−40°C to +125°C vs. 0°C to +70°C), making it suitable for harsher environments without layout or firmware changes.
