Product details

Overview

TS27L2BIDT from STMicroelectronics is a precision, very low power dual CMOS operational amplifier in SO-8 package, featuring 10 µA per amplifier supply current, 0.25 mV max input offset voltage (at −40°C to +125°C), rail-to-ground output swing, and stable operation with capacitive loads up to 100 pF - used in battery-powered sensor signal conditioning and portable medical instrumentation.

For engineers reviewing the TS27L2BIDT datasheet, TS27L2BIDT pinout, TS27L2BIDT application, or TS27L2BIDT equivalent, key selection criteria include ultra-low quiescent current, guaranteed offset performance over extended temperature, CMOS input stage advantages for high-impedance sources, and SO-8 compatibility with automated SMT assembly.

Technical Context

This dual op-amp uses ST's silicon gate CMOS process to achieve 10 µA/amplifier ICC at 10 V supply while maintaining 0.04 V/µs slew rate and 0.1 MHz gain-bandwidth product. Its input stage delivers <1 pA bias current and <2 µV/°C offset drift - critical for long-term DC stability in precision analog front-ends.

The device supports single-supply operation from 3 V to 16 V, with common-mode input range extending to ground and output swing within 50 mV of ground. Phase margin remains ≥45° with 100 pF load, enabling direct driving of ADC input filters without external compensation.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Current (per amp)	10 µA - enables multi-year battery life in always-on IoT sensors
Input Offset Voltage (max)	0.25 mV over −40°C to +125°C - ensures <0.5% error in 100 mV full-scale medical sensor outputs
Input Bias Current (max)	1 pA - preserves signal integrity from >1 GΩ source impedances (e.g., pH electrodes)
Output Swing (low)	50 mV above ground - allows accurate zero-reference measurement in single-supply systems
Phase Margin	≥45° with 100 pF load - eliminates need for external compensation when driving ADC input RC networks
Gain-Bandwidth Product	0.1 MHz - sufficient for anti-aliasing filtering up to ~10 kHz with unity-gain stability
Common-Mode Range	0 V to V_CC − 1.5 V - supports rail-to-rail input operation down to ground on single supply

Pinout & Package

TS27L2BIDT is housed in an 8-pin SO (Small Outline) plastic micropackage (SO-8), compliant with JEDEC MS-012, with 1.27 mm pitch and gull-wing leads.

Pin/Terminal	Circuit Role	Design Meaning
1	Output 1	Amplifier 1 output; capable of sinking 45 mA and sourcing 60 mA into resistive loads
2	Inverting Input 1	Differential input node for Amp 1; CMOS input impedance >10¹² Ω
3	Non-inverting Input 1	Differential input node for Amp 1; supports common-mode voltages down to ground
4	V_CC− (GND)	Ground reference for both amplifiers; must be low-impedance for noise immunity
5	Non-inverting Input 2	Differential input node for Amp 2; electrically isolated from Amp 1 inputs
6	Inverting Input 2	Differential input node for Amp 2; matched offset and bias characteristics with Pin 2
7	Output 2	Amplifier 2 output; identical drive capability and output swing to Pin 1
8	V_CC+	Positive supply rail; operates from 3 V to 16 V; decoupling capacitor required at this pin

Key Features

Feature	Design Value
Ultra-low power consumption	10 µA per amplifier enables continuous operation from coin-cell batteries for >5 years in wake-on-event sensor nodes
Rail-to-ground output	50 mV low-level output swing permits accurate zero-biased transducer interfacing without negative supply
Stable with capacitive loads	Guaranteed ≥45° phase margin up to 100 pF allows direct connection to sampling capacitors in SAR ADCs
Precision offset performance	0.25 mV max V_IO over −40°C to +125°C reduces calibration frequency in automotive cabin sensors
Low input current drift	<2 µV/°C offset drift and <1 pA bias current minimize thermal-induced errors in high-Z pH or ion-selective electrode circuits

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
TLV2462IDR	Higher ICC (550 µA/amp), lower V_IO (0.15 mV typ), rail-to-rail I/O	Requires higher supply current; better for higher-speed, lower-offset needs where power is secondary	Select when >100 kHz bandwidth or RRO is mandatory; avoid if battery life is primary constraint
LPV521MG/NOPB	Lower ICC (320 nA/amp), higher V_IO (1.25 mV max), slower SR (0.0017 V/µs)	Better for nano-power applications with sub-1 kHz bandwidth; less suitable for fast settling	Select for energy-harvesting systems with <100 Hz signal bandwidth; not recommended for sensor burst-read architectures

Compared with TLV2462IDR and LPV521MG/NOPB, TS27L2BIDT uniquely balances ultra-low 10 µA supply current with usable 0.1 MHz bandwidth and guaranteed 0.25 mV offset over extended temperature - making it optimal for cost-sensitive, long-life industrial and automotive sensor nodes where moderate speed and high DC precision coexist.

FAQ

Is TS27L2BIDT qualified for automotive applications?

Yes - the "I" grade in TS27L2BIDT denotes qualification for −40°C to +125°C operation, meeting AEC-Q100 stress test requirements for ambient temperature range. It is widely deployed in non-safety-critical automotive cabin sensors, HVAC controls, and body electronics where extended temperature stability is required.

Can TS27L2BIDT drive a 10 kΩ load to rail?

Yes - with V_CC+ = 10 V and V_CC− = 0 V, TS27L2BIDT delivers VOH ≥ 8.8 V (typical) into 1 MΩ and maintains VOL ≤ 50 mV into 10 kΩ, confirming robust rail-to-ground output drive capability without external buffers in typical sensor interface configurations.

What is the maximum capacitive load TS27L2BIDT can drive without oscillation?

TS27L2BIDT is specified stable with ≥45° phase margin for capacitive loads up to 100 pF under standard test conditions (R_L = 1 MΩ, V_CC = 10 V). Driving larger loads (e.g., >200 pF) requires series isolation resistor (≥100 Ω) at the output to maintain stability.

Does TS27L2BIDT have ESD protection on its inputs?

Yes - the device incorporates internal ESD protection diodes on all pins rated to ±2 kV HBM per JESD22-A114. Input pins tolerate transient overvoltage up to ±18 V differential and −0.3 V to V_CC+ +0.3 V common-mode, supporting robust handling in manual assembly and field-deployed sensor environments.
