Product details

Overview

TS27M2IDT 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 targets battery-powered sensor signal conditioning, portable medical instrumentation, and industrial analog front-ends requiring stable DC precision and capacitive-load drive capability.

For engineers reviewing the TS27M2IDT datasheet, TS27M2IDT pinout, TS27M2IDT application, or TS27M2IDT equivalent, key selection criteria include input offset voltage (≤5 mV max at −40°C to +125°C), ultra-low bias current (≤300 pA), phase margin stability with 100 pF loads, and SO-8 package compatibility with legacy PCB footprints.

Technical Context

The TS27M2IDT implements a two-stage CMOS transconductance amplifier architecture with class-AB output stage, enabling rail-to-ground output swing while maintaining 45° phase margin into 100 pF capacitive loads. Its input stage uses matched PMOS differential pairs, yielding <300 pA input bias current and <2 µV/°C offset drift.

It operates across −40°C to +125°C with guaranteed performance at VCC = 10 V, supporting single-supply configurations where common-mode input range extends from ground to VCC − 1.5 V and output drives ≥34 mA sink / ≥45 mA source into resistive loads.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	3 V to 16 V - supports direct connection to Li-ion batteries (3.7 V), 5 V logic rails, and 12 V industrial supplies without regulation
Supply Current per Amp	150 µA typ - enables >1-year operation on CR2032 coin cell in always-on sensor nodes
Gain Bandwidth Product	1 MHz typ - sufficient for anti-aliasing filters up to ~100 kHz and closed-loop gain ≤100
Input Offset Voltage	≤5 mV max (−40°C to +125°C) - ensures ≤50 mV error in unity-gain buffer driving 10 kΩ load
Phase Margin	45° min with 100 pF load - guarantees stable step response without external compensation in transimpedance or DAC output stages
Output Swing	Rail-to-ground (VOL ≤50 mV @ 34 mA sink) - allows full-scale ADC interfacing with 0–VCC input range
Input Bias Current	≤300 pA max - preserves high-impedance sensor node accuracy (e.g., pH electrodes, piezoresistive bridges)

Pinout & Package

TS27M2IDT is supplied in an SO-8 (Small Outline) plastic micropackage, 5.0 mm × 6.2 mm body, 1.27 mm pitch, RoHS-compliant and ECOPACK® certified.

Pin/Terminal	Circuit Role	Design Meaning
1	Inverting Input (Amplifier 1)	High-impedance node accepting negative feedback or signal inversion; referenced to ground or virtual ground
2	Non-inverting Input (Amplifier 1)	DC-biased input for sensor reference or positive signal path; supports rail-to-rail common-mode range
3	Output (Amplifier 1)	Class-AB buffered output capable of sourcing 45 mA / sinking 34 mA into resistive loads
4	VCC− (Ground)	Power return terminal; must be connected to system ground plane with low-inductance path
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)	Second channel positive input; identical electrical specs to Pin 2
7	Output (Amplifier 2)	Second independent output; shares same thermal and supply coupling as Pin 3
8	VCC+	Positive supply rail (3–16 V); requires local 100 nF ceramic decoupling adjacent to Pin 8

Key Features

Feature	Design Value
Ultra-low quiescent current	150 µA per amplifier enables multi-year battery life in portable gas sensors and wearable ECG front-ends
Rail-to-ground output	VOL ≤50 mV at 34 mA sink allows direct interface to 0–VCC-input SAR ADCs without level-shifting circuitry
Capacitive-load stability	45° phase margin with 100 pF load eliminates need for isolation resistors in photodiode TIA designs
Wide temperature grade	−40°C to +125°C operation qualified per automotive ambient requirements (non-AEC-Q100)
Low input current drift	≤2 µV/°C offset drift and <300 pA bias current ensure stable calibration over industrial temperature cycles

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/amp), wider GBW (6.4 MHz), rail-to-rail I/O	Requires higher power budget; better for higher-frequency filtering but less suitable for multi-year battery use	Select when >100 kHz signal bandwidth or rail-to-rail input is mandatory
LMV358IDR	Lower Vio (7 mV max), higher ICC (130 µA/amp), no guaranteed phase margin >100 pF	Lacks capacitive-load stability assurance; may oscillate in photodiode TIA without series resistor	Select only for cost-sensitive, non-capacitive-load applications with relaxed offset tolerance

Compared with TLV2462IDR and LMV358IDR, TS27M2IDT uniquely balances ultra-low ICC (150 µA), verified 100 pF load stability, and −40°C to +125°C operation-making it optimal for long-life, thermally demanding, capacitively loaded analog sensing nodes where power and stability are co-constrained.

FAQ

What is the maximum capacitive load the TS27M2IDT can drive without oscillation?

The TS27M2IDT maintains 45° phase margin with up to 100 pF capacitive load under standard test conditions (VCC = 10 V, RL = 100 kΩ, Tamb = 25°C), as confirmed in Figure 11 of the datasheet. For loads exceeding 100 pF, external series resistance (≥10 Ω) at the output is recommended to preserve stability.

Does TS27M2IDT support true rail-to-rail input?

No. The TS27M2IDT features rail-to-ground output swing but has a limited common-mode input voltage range of 0 V to VCC − 1.5 V. It does not accept inputs within 1.5 V of the positive rail, unlike rail-to-rail input op-amps. This is specified in Table 2 (Vicm).

Can TS27M2IDT operate from a 3.3 V supply?

Yes. The device is fully specified down to 3 V supply (Table 2), delivering 150 µA/amp ICC, 1 MHz GBP, and functional output swing. At 3.3 V, VOL remains ≤50 mV at 34 mA sink, and VOH reaches ≥2.5 V - sufficient for interfacing with 3.3 V logic and ADCs.

Is TS27M2IDT qualified for automotive applications?

TS27M2IDT is rated for −40°C to +125°C operating temperature and carries industrial-grade qualification. While it meets ambient temperature requirements for many automotive subsystems (e.g., cabin sensors), it is not AEC-Q100 qualified and lacks automotive-specific reliability testing or PPAP documentation.
