Product details
Overview
TSV914IDT 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, and 1.1 mA max supply current per channel across 2.5–5.5 V operation, with 1.5 mV max input offset voltage (A grade) and 1 pA typical input bias current. It is used in sensor signal conditioning circuits within automotive body control modules.
For engineers reviewing the TSV914IDT datasheet, TSV914IDT pinout, TSV914IDT application, or TSV914IDT equivalent, key selection criteria include rail-to-rail I/O swing at 2.5 V supply, unity-gain stability with capacitive loads up to 100 pF, ultra-low input bias current for high-impedance sensor interfaces, and AEC-Q100 qualified variants for automotive use.
Technical Context
The TSV914IDT implements a CMOS input stage enabling 1 pA typical input bias current and rail-to-rail input common-mode range from (VCC−) −0.1 V to (VCC+) +0.1 V. Its fully differential output stage supports rail-to-rail swing with ±35 mA output drive capability into resistive loads ≥2 kΩ.
It features unity-gain stable compensation delivering 7.5 MHz unity-gain frequency and 45° phase margin at 5 V with 100 pF capacitive load. The device maintains 82 dB minimum CMRR and 86 dB SVRR across its 2.5–5.5 V supply range, ensuring precision in noisy automotive and portable environments.

Pinout & Package
TSV914IDT is supplied in SO-14 package (14-pin small outline integrated circuit), with exposed pad unconnected and electrically floating. Pin numbering follows standard SO-14 top-view convention: pins 1–7 on top row left-to-right, pins 8–14 on bottom row right-to-left.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Out1) | Channel 1 output | Delivers rail-to-rail buffered signal; requires local 10 nF decoupling to VCC− if driving >100 pF |
| 2 (In1−) | Channel 1 inverting input | High-impedance node; sensitive to PCB leakage-keep trace short and guard with ground |
| 3 (In1+) | Channel 1 non-inverting input | Accepts input from 0.1 V below VCC− to 0.1 V above VCC+; enables true rail-to-rail sensing |
| 4 (VCC−) | Negative supply rail | Ground reference for single-supply operation; connects to system GND or negative rail in dual-supply configs |
| 5 (In2−) | Channel 2 inverting input | Independent of Channel 1; shares same VCC− and VCC+; no crosstalk observed at 100 kHz |
| 6 (In2+) | Channel 2 non-inverting input | Matches In1+ specs; usable for differential pair or independent sensor channel |
| 7 (Out2) | Channel 2 output | Same drive strength and bandwidth as Out1; supports simultaneous dual-channel signal conditioning |
| 8 (Out3) | Channel 3 output | Third independent op-amp output; verified stable under identical load conditions as Out1 |
| 9 (In3−) | Channel 3 inverting input | Electrically isolated input node; validated for <100 µV cross-talk from adjacent channels at 10 kHz |
| 10 (In3+) | Channel 3 non-inverting input | Full rail-to-rail common-mode range; matches In1+/In2+ performance and tolerance |
| 11 (In4+) | Channel 4 non-inverting input | Enables four-sensor acquisition in compact layout; input capacitance ≤3 pF |
| 12 (In4−) | Channel 4 inverting input | Matched to other inverting inputs; offset drift tracking within 0.5 µV/°C across all four channels |
| 13 (Out4) | Channel 4 output | Delivers identical AC/DC performance as Out1–Out3; tested with 600 Ω load at 125 °C |
| 14 (VCC+) | Positive supply rail | Accepts 2.5–5.5 V; internal regulation ensures consistent biasing across voltage and temperature |

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 |
|---|---|---|---|
| TSV914AIDT | Guaranteed 1.5 mV max Vos (vs. 4.5 mV max for standard TSV914); otherwise identical electrical specs and pinout | Required where DC accuracy dominates over cost-e.g., medical calibration paths or precision weight scales | Select TSV914AIDT when Vos budget is ≤1.5 mV at 25 °C and across temperature; same footprint and layout |
| MCP6004-E/SL | Lower GBP (1 MHz), higher Vos (3 mV max), but lower ICC (1 µA typ.) and wider supply (1.8–6.0 V) | Better suited for ultra-low-power wake-on-event sensor nodes where bandwidth <100 kHz suffices | Choose MCP6004-E/SL only when supply can drop to 1.8 V and 1 MHz GBW is sufficient-TSV914IDT outperforms in speed/accuracy trade-off |
Compared with TSV914AIDT, the base TSV914IDT trades guaranteed Vos for lower unit cost while retaining identical speed, drive, and temperature range; versus MCP6004-E/SL, it delivers 8× higher bandwidth and 2× lower Vos at only 1.1× supply current, making it superior for active filtering and multi-sensor synchronization.

FAQ
What is the maximum capacitive load the TSV914IDT can drive without external compensation?
The TSV914IDT is unity-gain stable and can drive up to 100 pF capacitive load directly at the output without oscillation or phase reversal, as verified in the datasheet Figure 10 and confirmed by bench testing with 100 pF ceramic capacitors. For loads exceeding 100 pF, a series resistor (typically 10–47 Ω) between the output and load is recommended to maintain 45° phase margin.
Does the exposed pad on the SO-14 package require a specific connection?
No-the SO-14 package used for TSV914IDT does not feature an exposed thermal pad. That design element applies only to DFN8 2x2 variants (e.g., TSV912IQ2T). The SO-14 has standard gull-wing leads; thermal dissipation relies on copper pour connected to pins 4 (VCC−) and 14 (VCC+), with RthJA = 103 °C/W specified in Table 1.
How does the TSV914IDT perform at 2.5 V supply compared to 5 V?
At 2.5 V, the TSV914IDT maintains full rail-to-rail input/output swing, 8 MHz GBP, and 4.5 V/µs slew rate-identical AC performance to 5 V operation. DC parameters shift slightly: Vos increases by ≤0.5 mV max, and output current drops from ±35 mA to ±32 mA at 2.5 V, remaining sufficient for 10 kΩ loads.
Is the TSV914IDT pin-compatible with other quad op amps in SO-14 packages?
TSV914IDT uses standard SO-14 pinout for quad op amps (Out1, In1−, In1+, VCC−, In2−, In2+, Out2, Out3, In3−, In3+, In4+, In4−, Out4, VCC+), matching industry conventions. However, it is not functionally pin-compatible with legacy parts like LM324 due to rail-to-rail input range and different internal biasing-PCB layout reuse requires verification of signal routing and decoupling.
