Product details
Overview
TSV611AICT from STMicroelectronics is a rail-to-rail input/output CMOS operational amplifier optimized for ultra-low-power, low-voltage sensor signal conditioning. It delivers 120 kHz gain bandwidth, 10 µA supply current at 5 V, 800 µV max input offset voltage (A-grade), 1 pA typical input bias current, and operates from 1.5 V to 5.5 V - ideal for battery-powered smoke detectors and portable medical sensors.
For engineers reviewing the TSV611AICT datasheet, TSV611AICT pinout, TSV611AICT application, or TSV611AICT equivalent, key selection criteria include its rail-to-rail I/O capability at sub-2 V operation, guaranteed A-grade offset performance across -40 °C to 85 °C, and SC70-5 package suitability for space-constrained analog front-ends in wearable and IoT edge nodes.
Technical Context
The TSV611AICT employs complementary PMOS/NMOS input stages enabling true rail-to-rail input common-mode range from (VCC–) –0.1 V to (VCC+) +0.1 V, with no phase reversal. Its unity-gain-stable architecture supports stable operation with capacitive loads up to 100 pF in follower configuration.
It achieves 80 dB minimum CMRR and 93 dB typical PSRR at 5 V, while maintaining 0.04 V/µs slew rate and 105 nV/√Hz input noise density at 1 kHz - characteristics directly enabling precision DC-coupled amplification in high-impedance sensor interfaces without external trimming.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.5 V to 5.5 V - enables direct operation from single-cell Li-ion (3.0–3.7 V), alkaline (1.5 V), or regulated 3.3 V/5 V rails without level-shifting. |
| Supply Current | 10.5 µA typ at 5 V - allows >10-year battery life in always-on smoke detector circuits drawing <1 µA average system current. |
| Gain Bandwidth | 120 kHz typ - sufficient for anti-aliasing and sensor signal filtering up to ~10 kHz while preserving DC accuracy. |
| Input Offset Voltage | 800 µV max (A version) - ensures ≤0.8 mV baseline error in 12-bit ADC interfaces with 2.048 V reference (0.04% FSR). |
| Input Bias Current | 1 pA typ - prevents significant voltage drop across >100 MΩ source impedances (e.g., piezoresistive or electrochemical sensors). |
| Output Swing | Within 35 mV of rails at 10 kΩ load - delivers full dynamic range to low-voltage SAR ADCs with 0–VCC input range. |
| Operating Temp | -40 °C to +85 °C - qualified for industrial and consumer environmental classes without derating. |
Pinout & Package
TSV611AICT is housed in a 5-pin SC70-5 (SOT323-5) package - 2.0 mm × 2.1 mm footprint with 0.65 mm lead pitch, optimized for high-density PCB layouts in portable devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier output | Delivers rail-to-rail voltage swing; capable of sourcing 49 mA / sinking 42 mA at 5 V - drives ADC reference buffers or LED bias directly. |
| 2 (IN–) | Inverting input | High-impedance node (1 pA bias); connects to feedback network in transimpedance or difference amplifier configurations. |
| 3 (IN+) | Non-inverting input | Accepts signals from high-Z sources (e.g., thermistor dividers, pH electrodes); rail-to-rail common-mode range enables direct sensor connection. |
| 4 (VCC–) | Negative supply | Ground reference pin; must be decoupled with 10 nF capacitor placed within 2 mm for stable low-noise operation. |
| 5 (VCC+) | Positive supply | Accepts 1.5–5.5 V; internal ESD protection rated to 4 kV HBM ensures robustness in handling-sensitive assembly environments. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input & output | Enables full utilization of 1.5 V supply headroom - eliminates need for dual supplies or level-shifters in single-ended sensor interfaces. |
| Ultra-low input bias current (1 pA) | Preserves signal integrity from megohm-range sensors (e.g., photodiode, humidity, gas sensors) without requiring guard rings or active guarding. |
| A-grade offset voltage (≤800 µV) | Reduces or eliminates factory calibration for medical-grade temperature or pressure sensing where 12-bit accuracy is required. |
| Unity-gain stable | Supports direct use in voltage follower, active filter, and transimpedance configurations without external compensation components. |
| 100 pF capacitive load drive | Permits direct connection to ADC input capacitance or long PCB traces without oscillation - simplifies layout and reduces BOM count. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rail-to-rail, low-power op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP6001T-E/OT (Microchip) | 1 µA lower supply current (9 µA), but 1.6 mV max offset (non-A grade); 100 kHz GBW. | Lacks A-grade spec - requires external calibration for <0.1% accuracy; suitable only for cost-sensitive, non-precision uses. | Select only if offset drift and calibration overhead are acceptable trade-offs for marginal power reduction. |
| TLV851DBVR (TI) | Higher 15 µA supply current; 1.5 mV max offset; 500 kHz GBW; supports 1.8–6 V supply. | Better bandwidth but higher power - unsuitable for multi-year battery life; better for higher-speed sensor sampling. | Prefer when >200 kHz signal bandwidth is required and 5 µA extra current is tolerable in the system budget. |
Compared with MCP6001T-E/OT and TLV851DBVR, the TSV611AICT uniquely balances A-grade precision (≤800 µV offset), ultra-low 10.5 µA consumption, and 120 kHz bandwidth in a 2.0 × 2.1 mm SC70 package - making it optimal for space- and energy-constrained precision analog front-ends where calibration is impractical.

FAQ
What is the maximum capacitive load the TSV611AICT can drive without external compensation?
The TSV611AICT is specified to drive up to 100 pF capacitive load stably in unity-gain follower configuration without oscillation, per STMicroelectronics' application note AN4272. This capability eliminates need for series output resistors in most ADC interface and sensor buffering applications, provided PCB layout follows recommended 10 nF local decoupling and short trace routing.
Does the TSV611AICT support operation below 1.8 V, and what performance is guaranteed?
Yes - the TSV611AICT is fully characterized down to 1.5 V supply, with all key parameters including 120 kHz gain bandwidth, 10 µA supply current, and rail-to-rail input/output maintained. Electrical characteristics tables explicitly include data at 1.8 V, 3.3 V, and 5 V, and Figure 1 confirms stable ICC vs. VCC down to 1.5 V across temperature.
How does the A-grade (TSV611AICT) differ from standard TSV611ICT in practical design terms?
The "A" suffix denotes tighter input offset voltage specification: 800 µV maximum (vs. 2 mV for standard grade) and 2 µV/°C drift (vs. 5 µV/°C). In practice, this eliminates first-order calibration in 12-bit systems using 2.048 V references, reduces thermal drift-induced error in ambient temperature sensors by >60%, and improves long-term stability in unattended monitoring equipment.
Can the TSV611AICT be used in single-supply active filter designs, and what topology is recommended?
Yes - its rail-to-rail input/output and unity-gain stability make it well-suited for Sallen-Key and multiple-feedback active filters operating on single 1.5–5.5 V supplies. ST recommends biasing the non-inverting input at mid-rail (e.g., via resistor divider + bypass cap) and using ceramic feedback networks; Figure 15 in the datasheet validates 2nd-order low-pass response at 1.8 V with <0.5 dB passband ripple.
