Product details

Overview

TS27L2AID from STMicroelectronics is a precision, very low power CMOS dual operational amplifier in SO8 package, featuring 10 µA per amplifier supply current, 0.25 mV max input offset voltage (TS27L2AI grade), rail-to-ground output swing, and 0.1 MHz gain-bandwidth product. It operates from 3 V to 16 V single supply and is designed for battery-powered sensor signal conditioning and portable instrumentation.

For engineers reviewing the TS27L2AID datasheet, TS27L2AID pinout, TS27L2AID application, or TS27L2AID equivalent, key selection criteria include ultra-low quiescent current, guaranteed low offset drift (2 µV/°C), high CMRR (80 dB), stable operation with capacitive loads, and industrial temperature range (–40°C to +125°C).

Technical Context

This dual op-amp uses ST's silicon-gate CMOS process to achieve exceptional input impedance (>10¹² Ω) and ultra-low input bias current (1 pA typ., 200 pA max over temperature). Its architecture enables stable unity-gain operation with up to 100 pF capacitive load without external compensation.

The device features fully independent amplifiers with common-mode input range extending to ground and output swing to within 50 mV of ground. Its phase margin remains ≥45° across supply voltages (3–16 V) and load conditions, supporting robust performance in low-noise, low-power analog front-ends.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Current	10 µA per amplifier - enables multi-year battery life in always-on sensor nodes
Input Offset Voltage	0.25 mV max (TS27L2AI) - supports DC-coupled precision measurement without trimming
Gain-Bandwidth Product	0.1 MHz - suitable for low-frequency signal conditioning (e.g., thermocouple, RTD, pH)
Common-Mode Range	0 V to V_CC – 1.5 V - allows direct interface with grounded sensors and single-supply ADCs
Output Swing	to ground (50 mV low-level) - preserves dynamic range in low-voltage systems
Phase Margin	≥45° at unity gain - ensures stability with capacitive loads up to 100 pF
CMRR / PSRR	80 dB each - rejects supply noise and common-mode interference in noisy environments

Pinout & Package

TS27L2AID is housed in an 8-pin SO (Small Outline) plastic micropackage (SO8), compliant with JEDEC MS-012, 1.27 mm pitch, body size 4.9 × 6.0 mm.

Pin/Terminal	Circuit Role	Design Meaning
1	Output 1	Amplifier 1 output; rail-to-ground capable, drives 1 MΩ load or ≤100 pF capacitance
2	Inverting Input 1	High-impedance CMOS input (I_ib = 1 pA typ.); connects to feedback network
3	Non-inverting Input 1	High-impedance CMOS input; accepts signals from grounded sensors or resistive dividers
4	V_CC– (GND)	Ground reference for both amplifiers; must be low-impedance return path
5	Non-inverting Input 2	Independent high-Z input for second channel; identical specs to Pin 3
6	Inverting Input 2	Independent high-Z input for second channel; identical specs to Pin 2
7	Output 2	Amplifier 2 output; electrically isolated from Output 1; same drive capability
8	V_CC+	Positive supply rail (3–16 V); decoupling capacitor required near this pin

Key Features

Feature	Design Value
Ultra-low supply current	10 µA per amplifier - reduces system power budget by >90% vs. standard op-amps
Guaranteed low offset drift	2 µV/°C - eliminates thermal calibration in wide-temperature industrial sensors
Rail-to-ground output	50 mV low-level output - maximizes usable signal range in 3.3 V or lower systems
Capacitive-load stability	Stable with 100 pF load - enables direct driving of ADC input filters or long traces
High input impedance	>10¹² Ω - prevents loading of high-impedance sources (e.g., piezoelectric, pH electrodes)

Applications

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLC27L2CDR (TI)	10 µA I_CC, 1.3 mV V_io (max), SO8, –40°C to +85°C	Lower temp range; higher offset limits DC accuracy in extended industrial use	Select when cost sensitivity outweighs extended temperature or offset requirements
LPV521MG/NOPB (TI)	320 nA I_CC, 10 µV V_io (max), SC70-5, –40°C to +125°C	Single-channel, smaller package, lower power but no dual configuration or SO8 footprint	Select for ultra-low-power single-channel designs where board space is constrained

Compared with TLC27L2CDR and LPV521MG/NOPB, TS27L2AID uniquely balances ultra-low power (10 µA), dual-channel integration, industrial temperature rating, and SO8 compatibility-making it optimal for space-constrained, battery-operated dual-signal-path systems requiring guaranteed performance across –40°C to +125°C.

FAQ

Is TS27L2AID suitable for single-supply operation down to 3 V?

Yes. TS27L2AID is fully specified for 3 V to 16 V single-supply operation. Its input common-mode range extends to ground, and its output swings to within 50 mV of ground, enabling full utilization of the 3 V rail in sensor interface circuits without level-shifting.

Does TS27L2AID require external compensation for stability?

No. The TS27L2AID is internally compensated and remains stable with capacitive loads up to 100 pF at unity gain. Its phase margin stays ≥45° across supply voltages (3–16 V) and temperatures (–40°C to +125°C), eliminating need for external compensation networks.

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

The TS27L2AID is characterized for stable operation with up to 100 pF capacitive load at unity gain, as confirmed by Figure 8 in the datasheet. Driving larger loads (e.g., >200 pF) may reduce phase margin and require isolation resistor or external compensation.

How does the TS27L2AI grade differ from TS27L2C or TS27L2M?

TS27L2AI specifies tighter electrical parameters: 0.25 mV max input offset voltage (vs. 1.1 mV for C-grade), 2 µV/°C max offset drift (vs. 10 µV/°C for C-grade), and extended –40°C to +125°C operating range (vs. 0°C to +70°C for C-grade), making it suitable for industrial and automotive-adjacent applications.
