Product details
Overview
TSV6294IPT from STMicroelectronics is a quad rail-to-rail input/output CMOS operational amplifier optimized for micropower, low-voltage operation (1.5–5.5 V), delivering 1.3 MHz gain bandwidth at just 29 µA supply current per amplifier. It features 800 µV max input offset voltage (A version), 1 pA typical input bias current, and EMI hardening-making it suitable for precision sensor interfaces in portable medical instrumentation.
For engineers reviewing the TSV6294IPT datasheet, TSV6294IPT pinout, TSV6294IPT application, or TSV6294IPT equivalent, key selection considerations include minimum stable gain (+4 non-inverting / –3 inverting), shutdown capability (not present on TSV6294IPT), extended temperature range (–40 to +125 °C), and TSSOP-14 package compatibility with high-density PCB layouts.
Technical Context
The TSV6294IPT implements complementary PMOS/NMOS input stages enabling true rail-to-rail input common-mode range (VCC− − 0.1 V to VCC+ + 0.1 V) and output swing within 35 mV of both rails under 10 kΩ load. Its internal compensation ensures stability only at gains ≥ +4 (non-inverting) or ≤ –3 (inverting), with phase margin ≥60° verified at 1.3 MHz GBP and 20 pF load.
It lacks dedicated shutdown pins-unlike the TSV6293/TSV6295 variants-so power control requires external supply gating. DC accuracy is enhanced by factory-trimmed offset (≤800 µV max) and ultra-low drift (2 µV/°C), while EMI rejection exceeds 85 dB at 900 MHz, critical for noisy portable environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.5–5.5 V: Enables direct operation from single-cell Li-ion (3.0–4.2 V), coin cell (1.5–3.0 V), or regulated 3.3/5 V rails without level-shifting. |
| Gain Bandwidth Product | 1.3 MHz typ: Supports active filtering up to ~100 kHz with gain ≥10, e.g., 2nd-order anti-aliasing filters for 100 kSPS ADCs. |
| Input Offset Voltage | ≤800 µV max (A version): Ensures ≤0.8 mV error in 1 V full-scale sensor signal paths, critical for <12-bit precision applications. |
| Input Bias Current | 1 pA typ: Minimizes voltage error across high-impedance sources (e.g., pH electrodes, photodiode transimpedance feedback networks). |
| Common-Mode Rejection | ≥79 dB at 3.3 V: Rejects >7,900:1 of supply ripple or coupled noise in battery-powered front-end amplification. |
| EMI Rejection Ratio | ≥85 dB at 900 MHz: Maintains signal integrity near cellular RF modules without additional shielding or filtering. |
| Operating Temperature | –40 to +125 °C: Qualified for automotive cabin electronics, industrial handhelds, and medical devices requiring extended thermal robustness. |

| 12 | In4+ | Non-inverting input of amplifier D; completes quad channel set; layout symmetry critical for matching. |
| 13 | In4− | Inverting input of amplifier D; matched to In1−/In2−/In3− for consistent CMRR across channels. |
| 14 | Out4 | Output of amplifier D; supports independent loading; no cross-talk with Out1–Out3. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Input common-mode extends 0.1 V beyond rails; output drives within 35 mV of VCC+/VCC−, maximizing dynamic range in low-voltage systems. |

| EMI Hardening | 85 dB rejection at 900 MHz reduces susceptibility to GSM/Bluetooth interference without external ferrites or shielded enclosures. |
| High Accuracy | 800 µV max offset + 2 µV/°C drift allows DC-coupled thermistor or strain gauge amplification without calibration over temperature. |
| Wide Supply Range | 1.5–5.5 V operation eliminates need for separate LDOs when interfacing with mixed-voltage MCUs (e.g., 1.8 V core, 3.3 V I/O). |

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 |
|---|---|---|---|
| TSV6294IST | Same electrical specs, but in MiniSO-10 package (3.0 × 3.0 mm); lacks Pin 4 (VCC−) and Pin 8 (VCC+) - uses shared VCC/VSS pins instead. | MiniSO-10 footprint saves 40% board area vs. TSSOP-14 but limits thermal dissipation and high-current routing. | Select TSV6294IST only if space-constrained and total quiescent current <120 µA permits lower thermal mass. |
| TSV6394IPT | Higher supply current (60 µA), 2.4 MHz GBP, unity-gain stable, same TSSOP-14 package and pinout. | Supports gain = 1 configurations (e.g., voltage followers) where TSV6294IPT requires ≥+4 gain, simplifying design for unknown source impedances. | Choose TSV6394IPT when unity-gain stability or higher bandwidth is mandatory, accepting 2× current penalty. |
Compared with TSV6294IST, the TSV6294IPT offers superior thermal performance and standard TSSOP-14 layout compatibility; versus TSV6394IPT, it trades bandwidth and stability flexibility for 52% lower power-critical for multi-year battery life.

FAQ
Does TSV6294IPT have a shutdown function?
No, the TSV6294IPT does not include shutdown pins. Unlike the TSV6293 or TSV6295 variants, it lacks SHDN1/SHDN2 terminals. Power must be controlled externally via supply rail switching. The datasheet confirms shutdown functionality applies only to dual (TSV6293) and quad (TSV6295) versions with dedicated enable pins.
What is the minimum stable gain for TSV6294IPT?
The TSV6294IPT requires a minimum non-inverting gain of +4 or inverting gain of –3 for stability, verified with 20 pF load and 100 kΩ feedback. At lower gains, phase margin drops below 60°, risking oscillation. This is due to internal compensation optimized for bandwidth/power trade-off-not a limitation of layout or external components.
Can TSV6294IPT drive capacitive loads directly?
It is not recommended to drive >100 pF capacitive loads directly. The amplifier's low internal compensation capacitance makes it sensitive to capacitive loading, which can reduce phase margin and cause peaking or oscillation. For capacitive loads >50 pF, add a series isolation resistor (≥100 Ω) between output and load, as documented in Section 4.6 of the datasheet.
Is TSV6294IPT pin-compatible with other TSSOP-14 op-amps?
No-it follows ST's proprietary quad op-amp pinout (In1+, In1−, Out1, VCC−, In2+, In2−, Out2, VCC+, In3+, In3−, Out3, In4+, In4−, Out4), differing from industry-standard pinouts like the LM324 or TLV2464. Direct replacement requires PCB redesign; verify pin mapping before substitution.
