Product details
Overview
TSV914AIYPT from STMicroelectronics is a quad rail-to-rail input/output operational amplifier optimized for low-voltage, low-power applications. It delivers 8 MHz gain-bandwidth, 4.5 V/µs slew rate, 1.5 mV max input offset voltage (A grade), 1 pA typical input bias current, and operates from 2.5 V to 5.5 V supply - enabling precision signal conditioning in automotive sensor interfaces and portable medical instrumentation.
For engineers reviewing the TSV914AIYPT datasheet, TSV914AIYPT pinout, TSV914AIYPT application, or TSV914AIYPT equivalent, key selection criteria include its AEC-Q100 qualified TSSOP-14 package, rail-to-rail swing at ±1.25 V to ±2.75 V supply, unity-gain stability with 100 pF capacitive load drive, and ultra-low input current critical for high-impedance transducer interfacing.
Technical Context
The TSV914AIYPT implements a CMOS input stage enabling 1 pA input bias current and rail-to-rail input common-mode range (VCC− −0.1 V to VCC+ +0.1 V), paired with a robust output stage delivering ±35 mA drive capability and 4.5 V/µs slew rate. Its 8 MHz GBP is maintained across 2.5–5.5 V supply while consuming only 1.1 mA per channel maximum.
Designed for unity-gain stability, it achieves 45° phase margin with 100 pF capacitive load and exhibits 82 dB CMRR and 86 dB SVR at 5 V supply - making it suitable for single-supply active filtering and precision analog front-ends where DC accuracy and dynamic response must coexist under tight power budgets.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 8 MHz - supports stable closed-loop operation up to 100 kHz with gain ≥10, enabling anti-aliasing and reconstruction filters. |
| Input offset voltage (max) | 1.5 mV - ensures ≤0.03% full-scale error in 50 mV–5 V sensor signal amplification without trimming. |
| Supply current per channel | 1.1 mA max - enables four-channel operation at <4.5 mA total, ideal for battery-powered portable ECG monitors. |
| Input bias current (typ) | 1 pA - prevents >10 MΩ source impedance degradation, critical for pH electrode and piezoelectric sensor interfaces. |
| Output drive capability | ±35 mA - drives 600 Ω loads to rail with <150 mV saturation, supporting direct DAC buffer or LED driver stages. |
| Common-mode rejection ratio | 82 dB - rejects >12× common-mode noise in differential sensor bridges operating near supply rails. |
| Slew rate | 4.5 V/µs - reproduces 10 kHz sine waves at 20 Vpp without distortion, sufficient for audio preamp and motor control feedback paths. |
Pinout & Package
TSV914AIYPT is housed in an AEC-Q100 qualified TSSOP-14 package (4.9 mm × 6.4 mm × 1.05 mm height) with exposed thermal pad not internally connected - may be tied to VCC− or left floating for PCB thermal management.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Channel 1 output | Capable of sourcing/sinking ±35 mA; rail-to-rail swing enables full utilization of 2.5–5.5 V supply range. |
| 2 (IN1−) | Channel 1 inverting input | CMOS input with 1 pA bias current; accepts signals from VCC− −0.1 V to VCC+ +0.1 V. |
| 3 (IN1+) | Channel 1 non-inverting input | Matches IN1− characteristics; used for unity-gain buffers or high-Z sensor connections. |
| 4 (VCC−) | Negative supply rail | Ground reference for single-supply operation; exposed pad may be connected here for thermal relief. |
| 5 (IN2+) | Channel 2 non-inverting input | Independent high-impedance node; shares VCC−/VCC+ rails with other channels. |
| 6 (IN2−) | Channel 2 inverting input | Paired with OUT2 (Pin 7); supports dual-channel instrumentation amplifier configurations. |
| 7 (OUT2) | Channel 2 output | Electrically identical to OUT1; allows independent gain stages for multi-sensor systems. |
| 8 (NC) | No connect | Internally unconnected; must remain unconnected on PCB to avoid parasitic coupling. |
| 9 (OUT3) | Channel 3 output | Third independent output; enables 3-phase motor current sensing or triple-redundant safety monitoring. |
| 10 (IN3−) | Channel 3 inverting input | Supports simultaneous acquisition from three isolated signal sources with matched DC specs. |
| 11 (IN3+) | Channel 3 non-inverting input | Provides third high-Z input path; maintains 1.5 mV max offset across temperature (−40°C to 125°C). |
| 12 (VCC+) | Positive supply rail | Accepts 2.5–5.5 V; internal regulation ensures stable biasing across automotive battery fluctuations. |
| 13 (IN4+) | Channel 4 non-inverting input | Enables fourth analog channel without external multiplexing; reduces system latency in real-time control. |
| 14 (IN4−) | Channel 4 inverting input | Completes quad-channel architecture; all inputs share same 82 dB CMRR and 5 µV/°C drift spec. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Operates with input common-mode range extending 0.1 V beyond rails and output swing within 40 mV of rails at 10 kΩ load - maximizes dynamic range in 3.3 V microcontroller ADC interfaces. |
| Unity-gain stable with 100 pF load | Eliminates need for external compensation in capacitive sensor interfaces (e.g., touch panels, MEMS microphones) - reduces BOM count and layout area. |
| AEC-Q100 Grade 1 qualification | Rated for −40°C to +125°C ambient operation with production flow validated to automotive reliability standards - suitable for engine control and ADAS front-end circuits. |
| Low input offset voltage drift | 5 µV/°C max - limits total offset shift to <0.6 mV over full temperature range, enabling uncalibrated industrial temperature sensing. |
| ESD immunity ≥5 kV HBM | Withstands human-body model discharges during assembly and field service - improves yield in automotive module manufacturing environments. |

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 | Same die, SO-14 package; no AEC-Q100 qualification; 7.5 mV max offset (standard grade) | Non-automotive industrial use only; unsuitable for under-hood or safety-critical modules | Select when cost sensitivity outweighs automotive qualification and tighter offset spec. |
| TSV994AIYPT | Higher 20 MHz GBP; 10 V/µs slew rate; 1.2 mA supply current; same AEC-Q100 TSSOP-14 package | Required for >200 kHz signal bandwidths (e.g., ultrasonic flow meters, motor phase current sensing) | Choose when dynamic performance exceeds 8 MHz requirement and additional 0.1 mA/channel is acceptable. |
Compared with TSV914IDT, the TSV914AIYPT adds automotive qualification and tighter offset (1.5 mV vs. 7.5 mV) at identical price point; versus TSV994AIYPT, it trades 2.5× bandwidth for 11% lower quiescent current - optimizing for battery life over speed in sensor front-ends.

FAQ
Is TSV914AIYPT pin-compatible with standard quad op-amp TSSOP-14 footprints?
Yes - TSV914AIYPT uses industry-standard TSSOP-14 mechanical dimensions (4.9 mm × 6.4 mm, 0.65 mm pitch) per Table 10 in DS4899 Rev 13. Pin 1 (OUT1) aligns with standard marking conventions, and the exposed thermal pad is unconnected - allowing drop-in replacement in existing layouts designed for generic TSSOP-14 op-amps.
What is the maximum capacitive load the TSV914AIYPT can drive without external compensation?
The TSV914AIYPT is unity-gain stable and characterized to drive up to 100 pF capacitive load without oscillation, as verified in Figure 10 and Section 5.1 of DS4899. For loads exceeding 100 pF, ST recommends adding a 10–100 Ω series resistor at the output - values are specified in Figure 19 based on exact capacitance.
Does the exposed pad on the TSSOP-14 package require connection for thermal performance?
No - the exposed pad is not internally connected (per DS4899 Section 6.5). It may be left floating or soldered to a copper pour tied to VCC− for improved thermal dissipation. Thermal resistance junction-to-ambient is 100 °C/W (typical) with no pad connection, dropping to ~75 °C/W when pad is thermally anchored to 200 mm² inner-layer copper.
How does the TSV914AIYPT's input offset voltage compare across temperature?
At 25 °C, offset is ≤1.5 mV (A grade); over −40°C to +125°C, it remains ≤3.0 mV (Table 3–5, DS4899 Rev 13). Combined with 5 µV/°C drift, total variation stays within ±0.6 mV across the full range - enabling accurate DC-coupled measurements in automotive engine bay environments without calibration.
