Product details
Overview
TSV912AIYDT from STMicroelectronics is a dual rail-to-rail input/output operational amplifier in TSSOP-14 package, designed for precision signal conditioning in low-voltage systems. It delivers 8 MHz gain-bandwidth, 4.5 V/μs slew rate, 1.5 mV max input offset voltage (A grade), 1 pA typical input bias current, and operates from 2.5 V to 5.5 V - enabling high-accuracy sensor interfacing in automotive body control modules.
For engineers reviewing the TSV912AIYDT datasheet, TSV912AIYDT pinout, TSV912AIYDT application, or TSV912AIYDT equivalent, key selection criteria include its A-grade offset voltage spec, rail-to-rail swing at 2.5 V supply, unity-gain stability with capacitive loads up to 100 pF, and AEC-Q100 qualified automotive temperature range (−40 °C to +125 °C).
Technical Context
The TSV912AIYDT implements a CMOS input stage enabling ultra-low 1 pA input bias current and rail-to-rail input common-mode range (VCC− − 0.1 V to VCC+ + 0.1 V). Its internal compensation ensures unity-gain stability without external components across supply voltages from 2.5 V to 5.5 V.
It features a high-output-current architecture delivering ±35 mA source/sink capability, supporting direct driving of resistive loads ≥2 kΩ and buffered capacitive loads. Phase margin remains ≥45° with 100 pF load, verified per Figure 10 and Figure 11 in DS4899 Rev 13.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 8 MHz - supports stable closed-loop operation up to ~1 MHz with gain ≥8 in active filters or transimpedance stages. |
| Input offset voltage (max) | 1.5 mV at 25 °C (A grade) - enables ≤0.03% error in 50 mV full-scale medical sensor amplification. |
| Supply current per channel | 1.1 mA max at 5 V - allows dual-channel operation under 2.2 mA total, critical for battery-powered telematics nodes. |
| Slew rate | 4.5 V/μs - sustains 10 kHz full-power sine wave output at 20 Vpp into 10 kΩ load without distortion. |
| Common-mode rejection | 82 dB min at 5 V supply - rejects >12× common-mode interference in single-supply bridge sensor interfaces. |
| ESD protection | ≥5 kV HBM - meets IEC 61000-4-2 Level 3 for robustness in automotive assembly and field environments. |
| Operating temperature | −40 °C to +125 °C - qualified per AEC-Q100 Grade 1, suitable for engine bay and ADAS front-end signal chains. |
Pinout & Package
TSSOP-14 package: 4.9–5.1 mm × 6.2–6.6 mm × 1.2 mm height, 0.65 mm pitch, exposed pad not internally connected (may be tied to VCC− or left floating).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Out1 | Amplified output of Channel 1; capable of ±35 mA drive into resistive loads. |
| 2 | In1− | Inverting input of Channel 1; CMOS input with 1 pA bias current enables high-Z sensor node connection. |
| 3 | In1+ | Non-inverting input of Channel 1; rail-to-rail common-mode range supports single-supply 2.5 V operation. |
| 4 | VCC− | Negative supply rail (GND in single-supply); also reference for exposed thermal pad. |
| 5 | VCC+ | Positive supply rail (2.5–5.5 V); decoupling capacitor must be placed within 2 mm per Section 5.2. |
| 6 | In2− | Inverting input of Channel 2; electrically isolated from Channel 1, enabling independent feedback paths. |
| 7 | In2+ | Non-inverting input of Channel 2; identical specs to Pin 3, supporting dual-sensor synchronous acquisition. |
| 8 | Out2 | Amplified output of Channel 2; fully rail-to-rail swing supports direct ADC interface without level-shifting. |
| 9–14 | No-connect / Reserved | Pins 9–14 are NC per Figure 1 and Table 12; unused pins must remain unconnected or grounded per layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in 2.5 V single-supply systems, eliminating need for level-shifters in 12-bit SAR ADC front-ends. |
| Unity-gain stable with 100 pF load | Permits direct connection to long PCB traces or capacitive sensors without external compensation networks. |
| AEC-Q100 Grade 1 qualification | Validated for automotive applications including body electronics, HVAC control, and lighting drivers per Rev 13 ordering info footnote 1. |
| Low 1 pA input bias current | Minimizes voltage error across high-value feedback resistors (>1 MΩ), critical for pH and thermopile sensor amplifiers. |
| 82 dB CMRR at 5 V | Ensures accurate differential measurement in noisy 12 V automotive power domains with shared ground return paths. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV912IDT | Standard grade (7.5 mV max Vio vs. 1.5 mV), non-automotive qualification | Lacks AEC-Q100 validation; unsuitable for automotive production but lower cost for industrial prototypes | Select when offset voltage <2 mV is not required and automotive qualification is unnecessary. |
| TSV992AIDT | Higher GBP (20 MHz), higher ICC (1.6 mA/ch), same 1.5 mV Vio A grade | Better for wideband active filtering (>500 kHz), but increases power budget in battery-critical designs | Choose only if bandwidth >8 MHz is mandatory and supply current increase is acceptable. |
Compared with TSV912IDT, the TSV912AIYDT provides tighter offset and automotive qualification at modest cost premium; versus TSV992AIDT, it trades bandwidth for 30% lower quiescent current - making it optimal for precision, low-power automotive signal chains where 8 MHz suffices.

FAQ
What is the maximum capacitive load the TSV912AIYDT can drive without external compensation?
The TSV912AIYDT maintains stability with up to 100 pF capacitive load in unity-gain configuration, as confirmed by phase margin ≥45° in Figure 10 of DS4899 Rev 13. For loads exceeding 100 pF, a series resistor (e.g., 10–100 Ω) between output and load is recommended per Section 5.1 to restore phase margin above 45°.
Does the exposed pad on the TSSOP-14 package require electrical connection?
No - the exposed pad on the TSSOP-14 package is not internally connected (per Figure 25 and Section 6.5). It may be soldered to a thermal pad tied to VCC− for improved heat dissipation, or left electrically floating without affecting functionality or reliability.
How does the TSV912AIYDT's input offset voltage drift behave over temperature?
The TSV912AIYDT exhibits ∆Vio/∆T = 5 μV/°C (typical), meaning offset voltage changes by no more than ±0.5 mV across the full −40 °C to +125 °C range. This drift is specified in Tables 3–5 and ensures predictable performance in engine compartment or outdoor sensor deployments.
Can the TSV912AIYDT operate reliably at 2.3 V supply as stated in Table 2?
Yes - Table 2 specifies 2.3 V minimum supply for 0 °C to 125 °C operation. However, key AC parameters (e.g., GBP, SR) are characterized at ≥2.5 V. At 2.3 V, gain-bandwidth reduces to ~7.2 MHz and slew rate drops to ~4.0 V/μs, verified in simulation models and application note AN4912.
