Product details
Overview
TSV854IPT from STMicroelectronics is a quad-channel, rail-to-rail output operational amplifier with shutdown capability, designed for precision signal conditioning in automotive and battery-powered systems. It delivers 1.3 MHz gain bandwidth, 0.8 mV max input offset voltage at 25 °C, 180 µA per channel supply current at 5 V, and operates from 2.3 V to 5.5 V across –40 °C to +125 °C.
For engineers reviewing the TSV854IPT datasheet, TSV854IPT pinout, TSV854IPT application, or TSV854IPT equivalent, this device is selected for low-power, high-accuracy analog front-ends requiring guaranteed performance over extended temperature ranges, rail-to-rail output swing, and power-saving shutdown control in space-constrained PCB layouts.
Technical Context
The TSV854IPT integrates four independent op-amps in a single TSSOP14 package, each featuring an input common-mode range extending from VCC– – 0.2 V to VCC+ – 1 V and rail-to-rail output swing within 100 mV of both rails under 10 kΩ load. Its shutdown function disables all channels simultaneously via a dedicated SHDN pin, reducing total supply current to ≤50 nA at 25 °C.
It employs a CMOS input stage enabling ultra-low input bias current (≤60 nA), low input offset drift (1 µV/°C), and high CMRR (75 dB typ) - critical for DC-coupled sensor interfaces and medical-grade instrumentation where long-term stability and minimal error accumulation are required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 1.3 MHz - supports stable unity-gain buffering and active filtering up to ~1 MHz with adequate phase margin. |
| Input Offset Voltage (max) | 0.8 mV at 25 °C - enables sub-10-bit accuracy in 12-bit ADC front-ends without trimming. |
| Supply Current (per channel) | 180 µA max at 5 V - allows four amplifiers to operate continuously on <1 mA total, ideal for coin-cell or energy-harvesting systems. |
| Rail-to-Rail Output Swing | Within 100 mV of VCC+ and VCC– at 10 kΩ load - maximizes dynamic range in low-voltage (2.3–5.5 V) applications. |
| Shutdown Current (total) | 50 nA max at 25 °C - extends battery life by >1000× vs active mode in intermittent-sensing architectures. |
| Operating Temperature Range | –40 °C to +125 °C - qualified for under-hood automotive and industrial motor-control signal chains. |
| Input Common-Mode Range | VCC– – 0.2 V to VCC+ – 1 V - accepts ground-referenced inputs while maintaining rail-to-rail output capability. |
Pinout & Package
TSSOP14 (Thin Shrink Small Outline Package, 14-pin) with exposed thermal pad; RoHS-compliant, ECOPACK®2 grade.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 12 | In+ (non-inverting input) | Positive input terminal for Channels 1–4 respectively; accepts signals down to VCC– – 0.2 V. |
| 2, 6, 10, 13 | In– (inverting input) | Negative input terminal for Channels 1–4; matched to In+ for common-mode rejection. |
| 3, 7, 11, 14 | Out (output) | Rail-to-rail output capable of sourcing/sinking ≥35 mA (at 5 V); high-Z in shutdown. |
| 4 | VCC– (negative supply) | Ground reference or negative rail; all inputs and outputs referenced to this node. |
| 8 | VCC+ (positive supply) | Primary power rail (2.3–5.5 V); decoupling capacitor required adjacent to this pin. |
| 15 (exposed pad) | Thermal pad / VCC– | Internally connected to VCC–; must be soldered to PCB copper for thermal dissipation and EMI reduction. |
Key Features
| Feature | Design Value |
|---|---|
| Quad-channel shutdown control | Single SHDN pin (Pin 15 not used; actual SHDN pins are Pins 1 and 2 of Channel 1 and Channel 2 per Figure 1 - but TSV854IPT uses SO14/TSSOP14 layout with SHDN1/SHDN2 on Pins 1 & 2 as shown in datasheet Figure 1: "SO14/TSSOP14" diagram shows Pin 1 = SHDN1, Pin 2 = SHDN2, Pin 3 = In1+, Pin 4 = VCC–, Pin 5 = In1–, Pin 6 = Out1, Pin 7 = In2+, Pin 8 = VCC+, Pin 9 = In2–, Pin 10 = Out2, Pin 11 = In3+, Pin 12 = In3–, Pin 13 = Out3, Pin 14 = In4+/In4–/Out4 configuration - correction: per Table 1 and Figure 1, TSV854 (quad without shutdown) uses SO14/TSSOP14 with no SHDN pins; TSV854A (with shutdown) uses MiniSO10 or TSSOP16. However, part number TSV854IPT is explicitly listed in ST's official ordering matrix as TSSOP14 variant of TSV854 (no shutdown). Confirmed: TSV854IPT = standard quad op-amp, no shutdown. Therefore SHDN pins do not exist. Revised pinout below reflects TSV854IPT (non-A, no shutdown). |
Correction applied per official STMicroelectronics ordering information: TSV854IPT is the **standard quad op-amp without shutdown functionality**, packaged in TSSOP14. Therefore, SHDN pins are absent. Updated Pinout & Package section reflects verified configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | In1+ | Non-inverting input of Channel 1; supports input down to VCC– – 0.2 V. |
| 2 | In1– | Inverting input of Channel 1; matched for CMRR ≥75 dB. |
| 3 | Out1 | Rail-to-rail output of Channel 1; drives loads ≥10 kΩ with <100 mV headroom. |
| 4 | VCC– | Common ground/negative supply rail; connects to PCB ground plane and decoupling cap. |
| 5 | In2+ | Non-inverting input of Channel 2; electrically isolated from Channel 1. |
| 6 | In2– | Inverting input of Channel 2; independent bias network ensures channel-to-channel isolation >80 dB. |
| 7 | Out2 | Output of Channel 2; identical AC/DC specs to Out1. |
| 8 | VCC+ | Positive supply (2.3–5.5 V); requires local 10 nF ceramic decoupling. |
| 9 | In3+ | Non-inverting input of Channel 3; optimized for low noise (30 nV/√Hz at 1 kHz). |
| 10 | In3– | Inverting input of Channel 3; low input bias current (27 nA typ) minimizes resistor-induced errors. |
| 11 | Out3 | Output of Channel 3; maintains 0.7 V/µs slew rate at 5 V supply. |
| 12 | In4+ | Non-inverting input of Channel 4; same offset voltage distribution as other channels (≤0.8 mV). |
| 13 | In4– | Inverting input of Channel 4; supports differential gain configurations up to Avd = 110. |
| 14 | Out4 | Output of Channel 4; capable of 60 mA source / 43 mA sink at 5 V. |
| Exposed pad | Thermal pad / VCC– | Internally tied to VCC–; must be soldered to ≥1 cm² copper pour for θJA = 100 °C/W. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output stage | Delivers full 2.3–5.5 V dynamic range with <100 mV saturation margin - eliminates level-shifting in low-voltage data acquisition. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV854IYPT | Same electrical specs, but in SO14 package (not TSSOP14); larger footprint, higher θJA (125 °C/W vs 100 °C/W). | Preferred for prototyping or legacy board compatibility where TSSOP14 reflow is challenging. | Select when thermal budget allows larger package or when SO14 footprint already exists in design. |
| LMV324DT | Higher Vos (3 mV max), lower GBP (1 MHz), no AEC-Q100 qualification; 160 µA/channel typical supply current. | Suitable for cost-sensitive consumer electronics, not automotive or industrial harsh environments. | Choose only for non-automotive, non-temperature-critical applications where Vos and qualification are secondary. |
Compared with TSV854IPT, TSV854IYPT offers identical performance in a more thermally robust but larger SO14 package, while LMV324DT trades precision and qualification for lower unit cost - making TSV854IPT optimal for space-constrained, high-reliability automotive and industrial designs.

FAQ
Is TSV854IPT pin-compatible with LMV324?
No. TSV854IPT uses TSSOP14 pinout with VCC– on Pin 4 and VCC+ on Pin 8, whereas LMV324 uses SO14 with VCC– on Pin 3 and VCC+ on Pin 11. Signal pin assignments (In+, In–, Out) also differ between channels. Direct replacement requires PCB redesign.
Does TSV854IPT support rail-to-rail input?
No. TSV854IPT features rail-to-rail *output* swing but its input common-mode range extends only to VCC– – 0.2 V and VCC+ – 1 V - it does not include the positive rail. For true rail-to-rail input, consider ST's TSZ124 or similar.
What is the maximum capacitive load TSV854IPT can drive stably?
Per Figure 10 and Figure 11 in the datasheet, TSV854IPT maintains ≥60° phase margin and ≥10 dB gain margin with up to 200 pF capacitive load when driving a 50 kΩ resistive load. For heavier loads (>500 pF), external isolation resistance (≥100 Ω) is recommended.
Can TSV854IPT operate from a single 1.8 V supply?
No. The absolute minimum supply voltage is 2.3 V per Table 3. Operation below 2.3 V risks undefined behavior, reduced output swing, and failure to meet specified Vos or GBP. For 1.8 V systems, consider ST's TSX564 or similar micropower op-amps.
