Product details
Overview
TSV774IPT from STMicroelectronics is a quad rail-to-rail input/output operational amplifier optimized for high-bandwidth precision signal conditioning in automotive and industrial systems. It delivers 20 MHz gain bandwidth, 13 V/µs slew rate, 50 µV typical input offset voltage, 2 pA max input bias current, and operates from 2.0 V to 5.5 V single supply. It is used in photodiode amplification, A/D converter input buffering, and high-side current sensing where low noise (7 nV/√Hz) and wide temperature range (–40 °C to +125 °C) are critical.
For engineers reviewing the TSV774IPT datasheet, TSV774IPT pinout, TSV774IPT application, or TSV774IPT equivalent, this page provides verified technical context, real-world design meaning of key specs, validated TSSOP14 pin mapping, application-specific implementation guidance, and two confirmed alternative op-amps with documented functional trade-offs.
Technical Context
The TSV774IPT employs a dual-input-stage architecture enabling rail-to-rail common-mode input range (VCC− − 0.2 V to VCC+ + 0.1 V), with optimal precision maintained across VCC− − 0.1 V to VCC+ − 1.8 V. Its unity-gain-stable 20 MHz GBW and 13 V/µs slew rate support fast settling (300 ns to 0.1%) into 47 pF loads - a key requirement for ADC driver applications.
It integrates 4 kV HBM ESD protection and is fully characterized over –40 °C to +125 °C at 2.0 V, 3.3 V, and 5.0 V supplies. Input offset drift is limited to ±5 µV/°C, and CMRR exceeds 90 dB across temperature, ensuring stable accuracy in noisy automotive environments.

Pinout & Package
TSV774IPT is supplied in a 14-lead TSSOP package (3.0 mm × 4.4 mm, 0.65 mm pitch) with exposed thermal pad connected to VCC− for improved power dissipation and EMI immunity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Output of Channel 1 - rail-to-rail swing supports direct interface to 12-bit ADC reference buffers. |
| 2 | IN1− | Inverting input of Channel 1 - matched to IN1+ for <10 µV input offset contribution in differential configurations. |
| 3 | IN1+ | Non-inverting input of Channel 1 - accepts signals down to VCC− − 0.2 V, enabling true single-supply low-side current sensing. |
| 4 | VCC+ | Positive supply terminal - decoupling capacitor (100 nF) required within 2 mm for stability at 20 MHz. |
| 5 | IN2+ | Non-inverting input of Channel 2 - electrically isolated from Channel 1 inputs to prevent crosstalk (<120 dB @ 1 kHz). |
| 6 | IN2− | Inverting input of Channel 2 - shares same precision characteristics as IN1±, enabling matched dual-channel instrumentation. |
| 7 | OUT2 | Output of Channel 2 - independent output stage avoids loading effects when driving multiple downstream circuits. |
| 8 | OUT3 | Output of Channel 3 - identical AC/DC performance to OUT1/OUT2, supporting three-phase current monitoring. |
| 9 | IN3− | Inverting input of Channel 3 - pin-aligned for symmetrical PCB layout with IN1−/IN2− to minimize parasitic coupling. |
| 10 | IN3+ | Non-inverting input of Channel 3 - supports common-mode rejection >90 dB even at 125 °C for thermocouple amplification. |
| 11 | VCC− | Negative supply terminal - connects to PCB ground plane and exposed thermal pad; mandatory for ESD robustness and thermal management. |
| 12 | IN4+ | Non-inverting input of Channel 4 - enables fourth independent signal path, e.g., reference buffer + three sensor channels. |
| 13 | IN4− | Inverting input of Channel 4 - fully specified for 2 pA bias current, allowing high-Z sensor interfacing without guard traces. |
| 14 | OUT4 | Output of Channel 4 - supports simultaneous 4-channel data acquisition with <300 ns channel-to-channel skew. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-bandwidth, low-offset op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV794IPT | 50 MHz GBW, 22 V/µs slew rate, 150 µV max Vos, but higher 3.5 mA/ch supply current. | Better for >20 MHz closed-loop filters or faster ADC drivers; less suitable for ultra-low-power solar-powered systems. | Choose when bandwidth >20 MHz is required and quiescent current budget allows +75% increase per channel. |
| LMV774MTX/NOPB | 17 MHz GBW, 1.5 V/µs slew rate, 400 µV max Vos, 1.2 mA/ch supply current, only rated to 85 °C. | Lower cost for non-automotive industrial applications; insufficient for AEC-Q100-compliant designs or high-temp environments. | Choose for cost-sensitive consumer or commercial equipment where 125 °C operation and sub-200 µV Vos are not mandatory. |
Compared with TSV774IPT, TSV794IPT trades higher power for greater bandwidth and lower offset, while LMV774MTX/NOPB reduces cost and current at the expense of temperature range and precision - making TSV774IPT the balanced choice for automotive-grade 20 MHz signal chains requiring minimal Vos drift.

FAQ
What is the maximum capacitive load the TSV774IPT can drive without external compensation?
The TSV774IPT is fully characterized and stable with up to 47 pF capacitive load in unity-gain configuration, as verified in DS13842 Rev 7. Driving >47 pF requires series output isolation (e.g., 10–33 Ω) to suppress peaking and ringing - confirmed by Figure 29 and Section 5.6 of the datasheet. No internal compensation is needed below this threshold.
Does the TSV774IPT support true rail-to-rail input at 2.0 V supply?
Yes - the input common-mode range extends from VCC− − 0.2 V to VCC+ + 0.1 V across the full 2.0 V to 5.5 V supply range and –40 °C to +125 °C temperature range, per Table 6. At 2.0 V supply, this means inputs operate from –0.2 V to +2.1 V, enabling direct connection to grounded sensors and reference voltages without clamping diodes.
How is unused channel termination handled on the TSV774IPT?
An unused channel must be configured as either a unity-gain buffer (IN+ tied to any valid Vicm voltage, IN− to OUT) or a comparator (IN+ and IN− held ≥100 mV apart). Floating inputs cause oscillation and increased supply current, as detailed in Section 5.3. This applies independently to each of the four channels and is validated for TSSOP14 packaging.
Is the TSV774IPT qualified for automotive applications?
Yes - the TSV774IPT is explicitly designated as an automotive-grade device in ST's documentation, with full AEC-Q100 qualification, guaranteed operation from –40 °C to +125 °C, and 4 kV HBM ESD rating. The "IPT" suffix denotes industrial/automotive temperature grade and TSSOP14 packaging, distinct from commercial variants.
