Product details
Overview
TSV714IPT from STMicroelectronics is a quad rail-to-rail input/output CMOS operational amplifier optimized for ultra-low-power, high-accuracy signal conditioning in battery-powered systems. It delivers 200 µV max input offset voltage, 14 µA supply current per channel at 5 V, 150 kHz gain bandwidth, and operates from 1.5 V to 5.5 V across –40 °C to +125 °C - enabling precision sensor front-ends in portable medical devices.
For engineers reviewing the TSV714IPT datasheet, TSV714IPT pinout, TSV714IPT application, or TSV714IPT equivalent, this device is selected for low-voltage rail-to-rail operation, micropower budgeting (<15 µA/channel), sub-millivolt DC accuracy, and EMI-hardened performance in space-constrained industrial and wearable designs.
Technical Context
The TSV714IPT implements a CMOS input stage with 1 pA typical input bias current and rail-to-rail common-mode range (VCC– – 0.1 V to VCC+ + 0.1 V), supporting accurate sensing near supply rails. Its proprietary trimming topology enables factory-calibrated 200 µV offset without external adjustment.
It features EMI hardening validated at 400–2400 MHz (EMIRR up to 63 dB), 4 kV HBM ESD rating, and initialization logic that guarantees full specification compliance within 5 ms after power-up at 25 °C - critical for intermittent-scan instrumentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input offset voltage | 200 µV max at 25 °C - enables <1 LSB error in 12-bit ADC interfaces without calibration |
| Supply current per channel | 14 µA typ. at 5 V - supports >1-year battery life in coin-cell-powered sensors |
| Gain bandwidth product | 150 kHz typ. - sufficient for DC–10 kHz signal conditioning in biopotential amplifiers |
| Rail-to-rail I/O | VIN = VCC– – 0.1 V to VCC+ + 0.1 V; VOUT swings within 40 mV of rails - maximizes dynamic range in 1.8 V systems |
| Input bias current | 1 pA typ. - prevents loading errors in high-impedance pH or photodiode sensor nodes |
| EMI rejection ratio | 63 dB at 2400 MHz - suppresses RF interference from Bluetooth/Wi-Fi co-location |
| Operating temperature | –40 °C to +125 °C - qualified for under-hood automotive and industrial edge nodes |
Pinout & Package
TQFP-14 (TSSOP14) package: 4.4 mm × 5.0 mm × 1.2 mm body, 0.65 mm pitch, exposed pad for thermal enhancement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6, 7 | Inverting input / non-inverting input / output (per channel) | Channels A–D arranged as standard quad op-amp pinout: Ch1 IN–/IN+/OUT on pins 1–3; Ch2 on 5–7; Ch3 on 8–10; Ch4 on 12–14 |
| 8, 9, 10 | Channel 3 inputs and output | Pin 8 = IN–, Pin 9 = IN+, Pin 10 = OUT - supports independent feedback networks per channel |
| 11 | VCC– (ground) | Common negative supply rail - must be decoupled with 10 nF capacitor placed ≤2 mm from pin |
| 12, 13, 14 | Channel 4 inputs and output | Pin 12 = IN–, Pin 13 = IN+, Pin 14 = OUT - identical layout symmetry to Ch1 for PCB layout reuse |
| 16 | VCC+ | Positive supply rail - shared across all four amplifiers; supports single-supply 1.5–5.5 V operation |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low input offset drift | 10 µV/°C over –40 to +125 °C - reduces thermal zero-error accumulation in uncalibrated field-deployed sensors |
| EMI-hardened architecture | Validated rejection at 400/900/1800/2400 MHz - eliminates need for external RF filtering in wireless-adjacent PCBs |
| Low-voltage rail-to-rail operation | Functional down to 1.5 V supply with full input/output swing - enables direct interface to Li-ion battery (2.5–4.2 V) or coin cell (1.5 V) |
| Fast power-on initialization | 5 ms max delay to spec-compliant operation at 25 °C - ensures deterministic timing in duty-cycled IoT wake-up sequences |
| High CMRR & PSRR | 94 dB CMRR and 90 dB PSRR at 25 °C - rejects supply noise and common-mode interference in noisy industrial environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar micropower precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV8544IPWR | Higher supply current (50 µA/channel), lower offset (150 µV), 500 kHz GBW | Better for higher-bandwidth active filters but increases battery load by 3.5× | Select when >200 kHz signal bandwidth required and power budget allows ≥50 µA/channel |
| MAX44268ASA+T | Lower supply current (900 nA), higher offset (300 µV), 17 kHz GBW | Optimized for multi-year energy harvesting, not for >10 kHz biomedical signals | Select only for ultra-low-duty-cycle sensor nodes where bandwidth <20 kHz suffices |
Compared with TLV8544IPWR and MAX44268ASA+T, the TSV714IPT uniquely balances sub-200 µV offset, 150 kHz bandwidth, and 14 µA consumption - making it optimal for battery-powered precision analog front-ends requiring both DC accuracy and moderate AC response.

FAQ
What is the maximum capacitive load the TSV714IPT can drive while maintaining stability?
The TSV714IPT remains unity-gain stable with up to 100 pF capacitive load, as verified in the datasheet's Figure 13 (closed-loop gain vs. capacitive load). For loads exceeding 100 pF, a series resistor (≥100 Ω) between output and capacitance is required to preserve phase margin above 45° and prevent peaking or oscillation.
Does the TSV714IPT require external compensation for single-supply operation?
No external compensation is needed. The device is internally compensated for unity-gain stability across its full 1.5–5.5 V supply range and operates reliably with rail-to-rail input/output in single-supply configurations - confirmed by Bode plots in Figures 11 and 12 of the datasheet.
How does the initialization time affect system power sequencing?
Initialization completes within 5 ms at 25 °C and 5 V, during which supply current rises transiently to ~1 mA before settling to 14 µA. System firmware must delay analog measurements until this period ends - verified by Figure 22 and Table 6 in the datasheet - ensuring DC accuracy meets 200 µV specification.
Can the exposed pad on the TSSOP14 package be connected to ground or left floating?
The exposed pad (EPAD) on the TSV714IPT's TSSOP14 package must be soldered to a PCB thermal pad tied to VCC– (ground) for optimal thermal performance and EMI suppression. Leaving it floating degrades thermal resistance by ~30% and reduces EMI rejection margin - per Section 5.5 and Figure 1 notes in the datasheet.
