Product details

Overview

TS952IYPT from STMicroelectronics is a dual rail-to-rail input/output BiCMOS operational amplifier optimized for 3 V and 5 V systems, delivering 3 MHz gain-bandwidth, 1 V/µs slew rate, and 0.95 mA supply current per channel at 5 V - used in automotive signal conditioning and portable audio driver stages.

For engineers reviewing the TS952IYPT datasheet, TS952IYPT pinout, TS952IYPT application, or TS952IYPT equivalent, this device supports precise low-voltage analog signal amplification with rail-to-rail swing, high PSRR (80 dB), latch-up immunity, and AEC-Q100 qualified operation up to 125 °C.

Technical Context

The TS952IYPT implements a dual-channel BiCMOS architecture enabling rail-to-rail input common-mode range (V_DD − 0.2 V to V_CC + 0.2 V) and rail-to-rail output swing (within 100 mV of rails at 600 Ω load). It operates from 2.7 V to 12 V single supply or ±1.35 V to ±6 V dual supply.

Its 3 MHz GBP and 1 V/µs slew rate support medium-speed signal conditioning without phase margin degradation (60° at unity gain), while THD of 0.01% at 10 kHz ensures fidelity in DAC buffering and headphone drive applications.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	2.7 V to 12 V - enables direct integration into 3.3 V and 5 V embedded systems without level-shifting.
Gain Bandwidth Product	3 MHz - supports stable closed-loop gain up to ~30 at 100 kHz for active filter design.
Slew Rate	1 V/µs - sufficient for 20 kHz full-scale audio signals with <1% distortion at 4 V_pk-pk.
Input Offset Voltage	6–8 mV (max) - suitable for DC-coupled sensor interfaces requiring sub-10 mV accuracy.
Supply Current per Channel	0.95 mA at 5 V - enables dual-amplifier operation in battery-powered devices with <2 mA total quiescent draw.
Common-Mode Rejection	50–80 dB - rejects noise in industrial transducer signal chains with unbalanced PCB routing.
Output Short-Circuit Current	±10 mA - drives 600 Ω loads directly, including line outputs and small speakers.

Pinout & Package

TSSOP8 package: 3 mm × 3 mm body, 0.65 mm pitch, 1.05 mm height, lead-free ECOPACK® compliant.

Pin/Terminal	Circuit Role	Design Meaning
1	Inverting Input, Channel 1	High-impedance node accepting differential feedback for precision inverting configurations.
2	Non-inverting Input, Channel 1	Accepts reference or sensor signal with rail-to-rail common-mode range down to V_DD − 0.2 V.
3	Output, Channel 1	Delivers rail-to-rail swing (e.g., 0.08–4.92 V at 5 V supply) into 600 Ω loads.
4	V_DD (Ground / Negative Supply)	Reference terminal for single-supply operation; must be connected to system ground or negative rail.
5	V_CC (Positive Supply)	Primary power pin; accepts 2.7–12 V; decoupling capacitor required within 1 cm.
6	Non-inverting Input, Channel 2	Independent input stage identical to Pin 2; supports dual independent signal paths.
7	Inverting Input, Channel 2	Matches Pin 1 functionality; enables dual-opamp topologies like instrumentation amps.
8	Output, Channel 2	Second rail-to-rail output; electrically isolated from Channel 1 except via shared supply pins.

Key Features

Feature	Design Value
Rail-to-rail input common-mode range	Extends to V_DD − 0.2 V and V_CC + 0.2 V - eliminates need for input biasing in single-supply sensor front-ends.
Rail-to-rail output voltage swing	Within 100 mV of both rails at 600 Ω - maximizes dynamic range in 3.3 V ADC driver and headphone amplifier stages.
AEC-Q100 qualified (Grade 2)	Rated for −40 °C to +125 °C ambient operation - validated for under-hood automotive signal conditioning.
Latch-up immunity	Withstands 200 mA transient current - prevents destructive failure during ESD or supply sequencing faults.
Low THD + noise	0.01% THD at 10 kHz, 25 nV/√Hz input noise - preserves signal integrity in medical instrumentation and audio paths.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
TS952IPT	Same electrical specs but rated for −40 °C to +85 °C; non-automotive grade TSSOP8.	Lacks AEC-Q100 qualification; unsuitable for under-hood automotive use.	Select when cost sensitivity outweighs extended temperature or automotive compliance requirements.
LMV358IDR	Lower GBP (1 MHz), higher input offset (7 mV typ), no AEC-Q100 rating; SO8 only.	Not qualified for automotive; limited bandwidth restricts audio and filter use cases.	Choose only for basic DC-coupled industrial sensing where speed and qualification are secondary.

Compared with TS952IPT and LMV358IDR, the TS952IYPT uniquely combines AEC-Q100 Grade 2 qualification, rail-to-rail I/O, and 3 MHz bandwidth - making it the sole option among these three for safety-critical automotive signal chains requiring full temperature coverage and dynamic fidelity.

FAQ

Is TS952IYPT pin-compatible with TS952IPT?

Yes - both use identical TSSOP8 packaging and share identical pin numbering and function mapping per the DS1256 datasheet. The only differences are temperature rating (−40 °C to +125 °C vs. −40 °C to +85 °C) and AEC-Q100 qualification status. No PCB redesign is needed for migration.

What is the maximum capacitive load the TS952IYPT can drive without instability?

The TS952IYPT remains unity-gain stable with up to 100 pF capacitive load, as verified by phase margin ≥60° in the datasheet (Table 3, RL = 600 Ω, CL = 100 pF). For loads >100 pF, an isolation resistor (≥10 Ω) between output and capacitance is recommended to maintain stability.

Does TS952IYPT support true single-supply operation below 3 V?

Yes - the device is fully specified down to 2.7 V supply, with rail-to-rail input extending to V_DD − 0.2 V and output swing within 100 mV of both rails. At 2.7 V, supply current remains 0.9 mA per channel and GBP stays at 3 MHz, enabling reliable operation in coin-cell or energy-harvesting systems.

How does the latch-up immunity specification impact system-level ESD protection design?

The 200 mA latch-up immunity (per Absolute Maximum Ratings Table 1) means the device withstands transient currents up to that level without entering destructive latch-up - reducing dependency on external series resistors or TVS diodes in moderate-ESD environments. However, IEC 61000-4-2 Level 4 (8 kV contact) still requires external protection at board level.
