Product details
Overview
TSV912AIDR from Texas Instruments is a dual-channel, rail-to-rail input/output operational amplifier optimized for precision, low-power, single-supply signal conditioning. It delivers 8 MHz gain bandwidth, 18 nV/√Hz input voltage noise at 1 kHz, 550 µA typical quiescent current per channel, and ±1.5 mV maximum input offset voltage across –40°C to 125°C - enabling accurate sensor interfacing in battery-powered HVAC controllers.
For engineers reviewing the TSV912AIDR datasheet, TSV912AIDR pinout, TSV912AIDR application, or TSV912AIDR equivalent, key selection criteria include its rail-to-rail I/O swing with 2.5 V to 5.5 V supply operation, ultra-low 1 pA input bias current for high-impedance sources, and unity-gain stability with no phase reversal under overdrive.
Technical Context
The TSV912AIDR employs a complementary differential input stage (N- and P-channel pairs) enabling true rail-to-rail common-mode input range - extending 100 mV beyond both supply rails across 2.5 V–5.5 V operation. Its unity-gain stable architecture supports direct driving of SAR ADC inputs without external compensation.
It features integrated RFI-EMI rejection filtering, robust ±4-kV HBM ESD protection, and no phase reversal during input overdrive - critical for motor control feedback loops and medical sensor front-ends where signal integrity must be preserved under transient conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth | 8 MHz - enables stable closed-loop operation up to 100 kHz with G = 100, suitable for active filter and anti-aliasing stages before 1 MSPS ADCs. |
| Input Offset Voltage | ±1.5 mV max - ensures ≤0.03% full-scale error in 5 V-span 12-bit systems without trimming. |
| Quiescent Current | 550 µA per channel - allows dual-opamp operation on coin-cell or energy-harvested supplies for portable instrumentation. |
| Input Bias Current | 1 pA typical - preserves signal fidelity when amplifying outputs from >100 MΩ source impedances (e.g., pH electrodes, piezoresistive sensors). |
| Supply Range | 2.5 V to 5.5 V - supports direct interface with Li-ion (3.0–4.2 V), USB (5 V), and industrial 3.3 V logic domains. |
| Output Swing | Rail-to-rail - delivers >4.95 Vpp into 10 kΩ load at 5.5 V supply, maximizing dynamic range for low-voltage data acquisition. |
| ESD Protection | ±4 kV HBM - meets IEC 61000-4-2 Level 2 requirements for industrial control panel interfaces. |
Pinout & Package
TSV912AIDR is housed in an 8-pin SOIC (D) package measuring 3.91 mm × 4.90 mm, with exposed thermal pad connected to V– for enhanced power dissipation in continuous operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives downstream ADC input or transducer load; rail-to-rail swing supports full-scale utilization. |
| 2 | –IN A | Inverting input, channel A - accepts feedback network for precise gain setting in inverting configurations. |
| 3 | +IN A | Noninverting input, channel A - connects to high-impedance sensor node; 1 pA bias current minimizes loading error. |
| 4 | V– | Negative supply / ground reference - also serves as thermal and EMI return path via exposed die pad. |
| 5 | V+ | Positive supply - accepts 2.5–5.5 V; internal regulation enables stable operation across battery discharge profiles. |
| 6 | –IN B | Inverting input, channel B - enables dual-sensor monitoring (e.g., temperature + humidity) with matched DC performance. |
| 7 | OUT B | Amplifier B output - independent channel supports differential sensing or dual-path signal conditioning. |
| 8 | +IN B | Noninverting input, channel B - electrically isolated from channel A; CMRR ≥80 dB ensures crosstalk immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in 3.3 V or lower single-supply systems - eliminates level-shifting circuitry in portable medical devices. |
| Ultra-low input bias current (1 pA) | Permits direct connection to high-Z sensors (e.g., thermistors, photodiodes) without gain error or drift from leakage paths. |
| No phase reversal under overdrive | Prevents latch-up or erroneous control signals in motor current-sense amplifiers when fault transients exceed input rails. |
| Integrated RFI-EMI rejection filter | Suppresses 100 MHz–1 GHz noise from switching power supplies and wireless modules - critical for automotive infotainment audio preamps. |
| Extended temperature range (–40°C to 125°C) | Validates operation in under-hood automotive modules and industrial PLC analog I/O cards without derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV932IDR | Lower GBW (1.5 MHz), higher IQ (120 µA/channel), same SOIC-8 package and rail-to-rail I/O. | Not suitable for >50 kHz active filters or fast-settling ADC drivers; better for ultra-low-power battery monitors. | Select LMV932IDR only when bandwidth demand is <2 MHz and supply current is primary constraint. |
| MCP6022-I/SN | Higher offset (2.5 mV max), higher noise (25 nV/√Hz), same 2.7–5.5 V supply range and SOIC-8 footprint. | Acceptable for cost-sensitive consumer appliances but not for medical-grade precision or low-noise audio. | Choose MCP6022-I/SN for non-critical industrial controls where offset and noise margins are relaxed. |
Compared with LMV932IDR and MCP6022-I/SN, the TSV912AIDR provides superior bandwidth-noise-power trade-off: 8 MHz GBW and 18 nV/√Hz at 550 µA enables high-fidelity signal chains in space-constrained, thermally demanding environments where alternatives fall short in speed or precision.

FAQ
What is the maximum capacitive load the TSV912AIDR can drive while maintaining stability?
The TSV912AIDR remains stable with up to 300 pF capacitive load in unity-gain configuration, as verified by phase margin ≥55° across 10 pF–300 pF per Figure 31 of the SBOS878D datasheet. For loads >100 pF, adding a 10 Ω series resistor at the output improves step response overshoot without compromising bandwidth.
Does the TSV912AIDR support single-supply operation down to 2.5 V?
Yes, the TSV912AIDR is fully specified for 2.5 V to 5.5 V operation. At 2.5 V supply, it maintains rail-to-rail input range (–0.1 V to 2.6 V), 100 dB open-loop gain, and 4.5 V/µs slew rate - enabling use in energy-harvesting systems powered by thin-film batteries or RF harvesters.
How does the TSV912AIDR handle input overvoltage conditions beyond the supply rails?
The TSV912AIDR input pins are diode-clamped to the supply rails (per Section 7.1), limiting input current to ≤10 mA if driven >0.5 V beyond V+ or V–. This protects against transient overvoltage in motor control feedback paths, though external series resistors are recommended for sustained overvoltage exposure.
Is the TSV912AIDR pin-compatible with other dual op amps in SOIC-8 packages?
No - the TSV912AIDR uses a non-standard pinout: V– is on Pin 4 and V+ on Pin 8, unlike industry-standard dual op amps (e.g., LM358, TL072) where V– is Pin 4 and V+ is Pin 8 but channel assignments differ. PCB layout must follow TI's TSV912-specific schematic and footprint.
What is the typical settling time of the TSV912AIDR for a 2-V step at unity gain?
The TSV912AIDR achieves 0.5 µs settling to 0.1% and 1.0 µs to 0.01% for a 2-V step input under unity-gain conditions with 100 pF load (Section 7.7, tS parameter). This performance supports high-speed data acquisition in 12-bit systems sampling at ≥1 MSPS with minimal dead time.
