Product details
Overview
TSV914AIYDT 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 battery-powered medical instrumentation and automotive sensor interfaces.
For engineers reviewing the TSV914AIYDT datasheet, TSV914AIYDT pinout, TSV914AIYDT application, or TSV914AIYDT equivalent, key selection criteria include its A-grade offset voltage specification, rail-to-rail swing capability at 2.5 V, 125 °C automotive temperature rating, and SO14 package compatibility with legacy op-amp footprints in space-constrained embedded systems.
Technical Context
The TSV914AIYDT implements a unity-gain-stable CMOS input stage with ultra-low input bias current (1 pA typ.) and rail-to-rail output swing within 40 mV of supply rails at 10 kΩ load. Its 8 MHz GBP and 4.5 V/µs slew rate support stable closed-loop operation in active filtering and sensor front-end amplification up to ~100 kHz.
Designed for automotive-grade reliability, it meets AEC-Q100 Grade 1 qualification (-40 °C to +125 °C), features ≥5 kV HBM ESD protection, latch-up immunity to 200 mA, and operates with common-mode input range extended 0.1 V beyond rails - critical for single-supply interfacing with resistive sensors and transducers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 8 MHz - enables stable unity-gain buffer or 2nd-order active filter design up to ~100 kHz with phase margin ≥45°. |
| Input offset voltage (max) | 1.5 mV at 25 °C (A grade) - ensures ≤1.5 mV DC error in precision 12-bit ADC front-ends at 3.3 V full-scale. |
| Supply current per channel | 1.1 mA max at 5 V - supports four-channel operation under 4.4 mA total, suitable for always-on battery monitoring circuits. |
| Input bias current (typ.) | 1 pA - minimizes voltage error across high-impedance sources (e.g., pH electrodes, piezoelectric sensors). |
| Rail-to-rail I/O | Input common-mode range: (VCC−) −0.1 V to (VCC+) +0.1 V; output swing: within 40 mV of rails at 10 kΩ - enables full dynamic range utilization in 2.5 V–5.5 V single-supply systems. |
| Operating temperature | −40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood automotive applications including engine control and cabin air quality sensing. |
| Slew rate | 4.5 V/µs - supports clean 1 Vpp sine wave reproduction up to ~700 kHz before slew-induced distortion dominates. |
Pinout & Package
TSV914AIYDT is housed in a 14-lead SOIC (SO14) package with standard 1.27 mm pitch, compatible with automated assembly and legacy op-amp layouts. The exposed pad is not internally connected and may be left floating or tied to VCC− for thermal enhancement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Out1) | Channel 1 output | Delivers rail-to-rail sourced/sunk current up to ±35 mA; requires local 10 nF decoupling near pins 7/14. |
| 2 (In1−) | Channel 1 inverting input | High-impedance CMOS node; input bias current ≤10 pA over temperature - critical for high-Z sensor buffering. |
| 3 (In1+) | Channel 1 non-inverting input | Matches In1− in offset and drift; common-mode range extends 0.1 V beyond supply rails for single-supply flexibility. |
| 4 (VCC−) | Negative supply / ground reference | Return path for all four channels; connects to system ground or negative rail; exposed pad may be tied here. |
| 5 (In2−) | Channel 2 inverting input | Electrically isolated from other inputs; layout symmetry recommended to minimize crosstalk in multi-channel filters. |
| 6 (In2+) | Channel 2 non-inverting input | Paired with Pin 5; identical DC specs to Pin 3 - enables matched differential pair implementation. |
| 7 (Out2) | Channel 2 output | Independent output stage; no internal cross-coupling - allows separate gain settings per channel in multi-stage designs. |
| 8 (NC) | No connect | Not bonded; must remain unconnected per datasheet - avoids unintended parasitic coupling or EMI paths. |
| 9 (Out3) | Channel 3 output | Third independent output; supports triple-active-filter topologies without external buffering or multiplexing. |
| 10 (In3−) | Channel 3 inverting input | Same electrical characteristics as Pins 2 and 5 - enables consistent performance across all three used channels. |
| 11 (In3+) | Channel 3 non-inverting input | Matches Pin 10; supports simultaneous acquisition from three independent sensor elements with matched gain paths. |
| 12 (In4+) | Channel 4 non-inverting input | Final input terminal; paired with Pin 13 - completes quad-channel configuration for full-system analog front-end integration. |
| 13 (In4−) | Channel 4 inverting input | Provides fourth matched input pair; enables 4-channel simultaneous sampling in portable medical ECG or EEG modules. |
| 14 (Out4) | Channel 4 output | Fourth rail-to-rail output; capable of driving 600 Ω loads to ±150 mV from rails - sufficient for DAC output buffering. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full utilization of 2.5 V–5.5 V supply range in single-supply systems - eliminates level-shifting components in portable device signal chains. |

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 | Standard grade (7.5 mV max Vio vs. 1.5 mV); same SO14 package and AEC-Q100 qualification. | Acceptable where system calibration compensates for higher offset; lower cost for non-precision automotive subsystems. | Select when 12-bit accuracy is sufficient and budget constraints preclude A-grade pricing. |
| LMV324QDRQ1 | Lower GBP (1 MHz), higher supply current (170 µA/channel), wider offset range (7 mV max), but same AEC-Q100 Grade 1 rating. | Suitable for DC-coupled sensor buffers where bandwidth <100 kHz is adequate and power is less constrained. | Choose for cost-sensitive, low-bandwidth automotive applications where 8 MHz performance is unnecessary. |
Compared with TSV914IDT, the TSV914AIYDT provides tighter offset control critical for uncalibrated medical measurements; versus LMV324QDRQ1, it delivers 8× higher bandwidth and 5× lower input bias current - enabling higher-resolution, lower-noise signal chains in compact portable systems.

FAQ
What is the maximum capacitive load the TSV914AIYDT can drive without external compensation?
The TSV914AIYDT is unity-gain stable and can drive up to 100 pF capacitive load directly in follower configuration without oscillation, as verified in the datasheet's Figure 10 and Section 5.1. For loads exceeding 100 pF, a small series resistor (e.g., 10–100 Ω) at the output is recommended to maintain phase margin ≥45°.
Does the exposed pad on the SO14 package require connection?
No - the SO14 package used for TSV914AIYDT does not feature an exposed pad. That thermal pad specification applies only to the DFN8 2x2 variant (e.g., TSV912IQ2T). The SO14 (TSV914AIYDT) has standard gull-wing leads and no internal thermal pad; thermal dissipation relies on copper pour connected to pins 4 (VCC−) and 14 (VCC+).
How does the A-grade offset voltage specification impact system-level calibration?
The 1.5 mV max input offset voltage (A grade) at 25 °C reduces initial DC error to ≤0.045% of 3.3 V full-scale - enabling single-point calibration in many portable medical and automotive applications. Over −40 °C to +125 °C, max offset rises to 3 mV, still permitting simplified two-point (min/max temp) calibration instead of full multi-point routines.
Can TSV914AIYDT operate reliably at 2.3 V supply as stated in Table 2?
No - while Table 2 lists 2.3 V as a minimum for 0 °C to 125 °C operation, the device's guaranteed specifications (including GBP, slew rate, and output drive) are validated only from 2.5 V to 5.5 V per the Electrical Characteristics tables. Operation below 2.5 V may yield degraded bandwidth and increased distortion; 2.5 V is the practical minimum for production designs.
