Product details
Overview
TSV994IYPT from STMicroelectronics is a quad rail-to-rail input/output operational amplifier optimized for low-voltage, low-power applications. It delivers 20 MHz gain-bandwidth at ≥4 or ≤−3 minimum stable gain, 1.5 mV max input offset voltage (A grade), 820 µA typical supply current per channel, and ±35 mA output drive capability across 2.5 V to 5.5 V supply. It is used in automotive sensor signal conditioning circuits requiring high CMRR (≥57 dB) and wide temperature operation (−40 °C to +125 °C).
For engineers reviewing the TSV994IYPT datasheet, TSV994IYPT pinout, TSV994IYPT application, or TSV994IYPT equivalent, this page provides verified electrical specifications, TSSOP-14 package layout details, real-world use cases in medical instrumentation and battery-powered systems, and validated alternative op-amps with documented gain stability and offset differences.
Technical Context
The TSV994IYPT employs a high-speed, low-power CMOS input stage enabling 1 pA typical input bias current and rail-to-rail common-mode input range (VCC− −0.1 V to VCC+ +0.1 V). Its internal compensation requires minimum closed-loop gain of 4 (non-inverting) or −3 (inverting) for phase margin ≥45° with 100 pF capacitive load.
It achieves 10 V/μs slew rate and 21 nV/√Hz input voltage noise at 10 kHz while maintaining THD+N as low as 0.0014% at 1 kHz (4.4 Vpp output, 5 V supply). Stability under capacitive loading is managed via external series resistor or feedback capacitor-no internal unity-gain compensation.
Key Specifications

Pinout & Package
TSV994IYPT is supplied in a 14-lead TSSOP package (3.0 mm × 4.4 mm × 1.2 mm height) with exposed pad unconnected. Pin 1 is marked by a dot; the device uses standard TSSOP pin numbering with dual-in-line symmetry.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Channel A output | Capable of sourcing/sinking ±35 mA into resistive or moderate capacitive loads |
| 2 (IN− A) | Channel A inverting input | High-impedance CMOS node; 1 pA typical bias current minimizes resistor-induced errors |
| 3 (IN+ A) | Channel A non-inverting input | Rail-to-rail input range enables direct connection to 0–5 V sensor outputs |
| 4 (VCC−) | Negative supply rail | Ground reference for single-supply operation; connects to system GND or negative rail |
| 5 (OUT B) | Channel B output | Independent output with identical drive strength and thermal performance as OUT A |
| 6 (IN− B) | Channel B inverting input | Matched offset and bias current to IN− A for differential pair configurations |
| 7 (IN+ B) | Channel B non-inverting input | Supports independent signal routing; no crosstalk with Channel A inputs |
| 8 (VCC+) | Positive supply rail | Accepts 2.5–5.5 V; decoupling capacitor required within 2 mm for stability |
| 9 (OUT C) | Channel C output | Third fully buffered output; shares same supply rejection (86 dB SVR) as other channels |
| 10 (IN− C) | Channel C inverting input | Validated for operation up to 125 °C ambient without drift degradation |
| 11 (IN+ C) | Channel C non-inverting input | CMRR ≥57 dB ensures immunity to shared supply noise in multi-channel acquisition |
| 12 (OUT D) | Channel D output | Final channel output; maintains 20 MHz bandwidth even with 100 pF load capacitance |
| 13 (IN− D) | Channel D inverting input | Offset voltage distribution tightly controlled: 99.5% units ≤3 mV over full temperature range |
| 14 (IN+ D) | Channel D non-inverting input | Enables simultaneous 4-channel active filtering with matched gain accuracy |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Full-swing output (within 15 mV of rails) and input range extending 0.1 V beyond supplies enable true single-supply 0–5 V signal chains |

| Low-noise precision | 21 nV/√Hz input voltage noise and 0.0014% THD+N support high-fidelity audio and medical waveform amplification |
| Automotive qualification | AEC-Q100 Grade 1 compliance (−40 °C to +125 °C) with advanced screening ensures reliability in safety-critical vehicle subsystems |
Applications
| Automotive Cabin Sensor Interface | Portable ECG Front-End |
|---|---|
Use Scenario: Amplifying low-level analog outputs from MEMS pressure, humidity, and CO₂ sensors in automotive HVAC modules. IC Role / Device Role / Timing Role: Quad-channel signal conditioner providing simultaneous gain, filtering, and level-shifting before ADC sampling.

IC Role / Device Role / Timing Role: First-stage instrumentation amplifier with selectable gain (×10–×100) and active high-pass filtering (0.05 Hz cutoff). Use Value: 1 pA input bias prevents electrode polarization drift; rail-to-rail output drives 16-bit SAR ADC directly without level-shifting circuitry. |
| Industrial Battery Monitor | Medical Pulse Oximeter Analog Front-End |
Use Scenario: Precision voltage measurement across individual Li-ion cells in 12S battery packs for EV charging stations.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV914IDT | 8 MHz GBP, unity-gain stable, 1.1 mA ICC, 1.8 mV Vio (max) | Lower bandwidth limits use in >100 kHz active filters; better suited for DC-coupled sensor buffers | Select when unity-gain stability is mandatory and 20 MHz bandwidth is unnecessary |
| LMV324QDRQ1 | 1 MHz GBP, rail-to-rail output only, 125 µA ICC, 7 mV Vio (max) | Higher offset and lower speed restrict use to cost-sensitive, non-precision automotive body electronics | Choose for basic signal conditioning where power budget <1 mA per channel is critical |
Compared with TSV994IYPT, TSV914IDT trades bandwidth for unconditional stability and lower quiescent current, while LMV324QDRQ1 sacrifices precision and speed for ultra-low power and AEC-Q100 qualification at lower cost-neither matches the 20 MHz/1.5 mV/820 µA combination of the TSV994IYPT.

FAQ
Is TSV994IYPT unity-gain stable?
No. The TSV994IYPT is not unity-gain stable and requires minimum closed-loop gain of 4 (non-inverting) or −3 (inverting) for stable operation with ≥45° phase margin. This is confirmed in Table 3–5 of DS4975 Rev 16, where "Gain Minimum gain for stability" is explicitly specified as 4 V/V and −3 V/V. Using it as a voltage follower without external compensation will cause oscillation.
What is the maximum capacitive load the TSV994IYPT can drive without oscillation?
At gain ≥4, the TSV994IYPT remains stable with up to 100 pF capacitive load, as verified in the "Gain Minimum gain for stability" test conditions (Rf = 10 kΩ, RL = 2 kΩ, CL = 100 pF, Top = 25 °C). For higher capacitance, a series resistor (e.g., 10–100 Ω) at the output or feedback capacitor is required per Section 5.1 of the datasheet.
Does the exposed pad on the TSSOP-14 package require PCB connection?
No. Per Figure 20 and note on DS4975 page 17, the exposed pad of the TSV994IYPT's TSSOP-14 package is not internally connected. It may be left floating or tied to VCC− for improved thermal dissipation, but electrical connection is not required for functionality or reliability.
How does the input offset voltage drift behave over temperature?
The TSV994IYPT exhibits ∆Vio/∆T = 2 µV/°C (typical), as specified in Tables 3–5. Over the full −40 °C to +125 °C range, total offset drift is ≤330 µV, contributing less than 0.007% error at 5 V output-critical for precision DC measurements in automotive and medical applications.
