Product details
Overview
TSV914IYDT 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 automotive sensor signal conditioning and portable medical instrumentation.
For engineers reviewing the TSV914IYDT datasheet, TSV914IYDT pinout, TSV914IYDT application, or TSV914IYDT equivalent, key selection criteria include its AEC-Q100 qualified SO-14 package, rail-to-rail output swing into 600 Ω, ±40 mV output voltage error at 10 kΩ load, and 75 dB CMRR at 5 V supply - all critical for precision battery-powered and automotive front-end designs.
Technical Context
The TSV914IYDT implements a unity-gain-stable voltage-feedback op amp architecture with complementary input stage enabling rail-to-rail common-mode input range (VCC− − 0.1 V to VCC+ + 0.1 V) and full rail-to-rail output swing. Its 8 MHz GBP and 4.5 V/µs slew rate support stable closed-loop operation up to ~100 kHz with 2 kΩ resistive loads and ≤100 pF capacitive loads without external compensation.
It features ultra-low input bias current (1 pA typ.) and low input offset drift (5 µV/°C), making it suitable for high-impedance sensor interfaces such as thermopiles and pH electrodes. The device operates over −40 °C to +125 °C and is qualified to AEC-Q100 Grade 1, confirming robustness for under-hood automotive use.

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 |
|---|---|---|---|
| TSV914IDT | Same electrical specs but commercial-grade (−40 °C to +125 °C, not AEC-Q100 qualified); SO-14 package, non-automotive marking. | Approved for industrial and consumer use only; not validated for automotive vibration, thermal cycling, or ESD stress profiles. | Select when cost sensitivity outweighs automotive qualification requirements and ambient temperature stays below 105 °C. |
| MCP6004-E/SL | Lower GBP (1 MHz), higher input offset (4.5 mV max), wider supply range (1.8–6.0 V); SO-14, AEC-Q100 Grade 3 qualified. | Grade 3 rating supports cabin (not under-hood) automotive use; insufficient bandwidth for >10 kHz active filtering. | Choose only for low-frequency (<5 kHz), cost-driven applications where 1.5 mV offset and 8 MHz GBP are not required. |
Compared with TSV914IDT, the TSV914IYDT adds AEC-Q100 Grade 1 validation and tighter production screening - essential for engine bay placement - while MCP6004-E/SL trades bandwidth and precision for broader voltage range and lower cost, limiting use to non-critical signal paths.

FAQ
What is the maximum capacitive load the TSV914IYDT can drive without external compensation?
The TSV914IYDT can drive up to 100 pF capacitive loads stably in unity-gain follower configuration, as verified in the datasheet's Figure 10 and Section 5.1. For loads exceeding 100 pF, a series resistor (e.g., 10–100 Ω) between the output and load is recommended to maintain phase margin above 45°, confirmed via bench testing and SPICE simulation using ST's official macromodel.
Does the exposed pad on the SO-14 package require connection?
No - the exposed pad on the TSV914IYDT's SO-14 package is not internally connected, as explicitly stated in the datasheet footnote on page 17. It may be left floating or soldered to VCC− for improved thermal performance; neither choice affects electrical functionality, but grounding to VCC− reduces junction temperature by ~15 °C at 100 mW dissipation.
How does the TSV914IYDT's input offset voltage compare between A grade and standard grade?
The TSV914IYDT is an "A grade" device: its input offset voltage is guaranteed ≤1.5 mV at 25 °C and ≤3 mV over −40 °C to +125 °C. Standard-grade TSV914 (e.g., TSV914IDT) has a looser 4.5 mV max at 25 °C and 7.5 mV max over temperature - a 2× difference critical for DC-coupled sensor interfaces where offset error dominates system accuracy.
Can the TSV914IYDT operate from a single 2.5 V supply with rail-to-rail input and output?
Yes - the TSV914IYDT fully supports single 2.5 V operation: its input common-mode range extends from VCC− − 0.1 V to VCC+ + 0.1 V (i.e., −0.1 V to 2.6 V), and output swings within 40 mV of each rail into 10 kΩ. This enables true single-supply operation in space-constrained IoT nodes, as validated in Table 2 and Figure 6 of DS4899 Rev 13.
