Product details
Overview
TLV2470IDBVT from Texas Instruments is a single-channel, rail-to-rail input/output CMOS operational amplifier with shutdown functionality in SOT-23-6 package. It delivers 2.8MHz gain-bandwidth, 600μA/channel supply current, ±10mA output drive at 180mV from rails, and 250μV typical input offset voltage - enabling precision low-power signal conditioning in battery-operated sensor interfaces.
For engineers reviewing the TLV2470IDBVT datasheet, TLV2470IDBVT pinout, TLV2470IDBVT application, or TLV2470IDBVT equivalent, this page provides verified pin functions, real-world use cases in portable medical and industrial sensing, confirmed shutdown behavior (350nA/ch @ 3V), and validated alternative op-amps for rail-to-rail I/O, micropower, and shutdown-capable designs.
Technical Context
The TLV2470IDBVT employs a CMOS input stage delivering 2.5pA input bias current and rail-to-rail common-mode input range (0V to VDD). Its output stage supports true rail-to-rail swing - reaching within 180mV of both supply rails under ±10mA load - while maintaining stability with capacitive loads ≥10pF when using a series nulling resistor (RNULL ≥20Ω).
Shutdown is controlled via a dedicated logic-input pin (SHDN) that places the output in high-impedance state and reduces supply current to 350nA/channel at 3V (1000nA at 5V). The device operates across –40°C to +125°C and is fully specified at 3V and 5V supply voltages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 6V - supports single-cell Li-ion (3.0–3.7V) and dual-AA (3.0V) systems without level-shifting. |
| Gain-Bandwidth Product | 2.8MHz - enables stable unity-gain buffer or closed-loop gain ≥10 up to ~280kHz. |
| Input Offset Voltage (typ) | 250μV - ensures ≤0.5mV error in 2V full-scale 12-bit ADC front-end with gain=2. |
| Supply Current (active) | 600μA/channel - draws only 1.8mW at 3V, suitable for multi-day battery life in portable sensors. |
| Shutdown Current (typ @ 3V) | 350nA/channel - reduces system standby power by >99.9% vs active mode. |
| Output Drive Capability | ±10mA at 180mV from rail - drives 10kΩ load to full scale with <0.5% linearity error. |
| Input Bias Current | 2.5pA - minimizes voltage error across high-impedance sources (e.g., pH electrodes, photodiodes). |
Pinout & Package
SOT-23-6 package: 2.9mm × 1.6mm × 1.1mm body, gull-wing leads, moisture sensitivity level 1, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier output | Delivers rail-to-rail voltage swing; high-impedance during shutdown. |
| 2 (IN−) | Inverting input | High-impedance CMOS node; accepts signals from 0V to VDD. |
| 3 (IN+) | Non-inverting input | High-impedance CMOS node; accepts signals from 0V to VDD. |
| 4 (GND) | Analog ground reference | Must be connected directly to PCB ground plane; separates analog return from digital/switching paths. |
| 5 (SHDN) | Shutdown control input | Active-low logic: ≤0.8V = shutdown (350nA), ≥2.0V = active (600μA); no pull-up required. |
| 6 (VDD) | Positive supply | Accepts 2.7–6V; bypass with 0.1μF ceramic capacitor placed ≤2mm from pin. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in 3V systems - e.g., 0–3V sensor output digitized by 3V ADC without level shift. |
| Ultra-low shutdown current (350nA @ 3V) | Extends battery life in intermittent-sampling applications - e.g., wireless temperature node waking every 60s draws <1μA average. |
| 600μA/channel supply current | Provides 2.8MHz bandwidth at micropower level - outperforms legacy 200μA op-amps by >10× AC performance. |
| 2.5pA input bias current | Reduces offset drift in high-Z transducer interfaces - critical for thermopile or piezoelectric sensor signal chains. |
| Stable with RNULL ≥20Ω into capacitive loads | Allows direct driving of ADC input capacitance (typically 10–20pF) without oscillation or settling degradation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rail-to-rail, micropower operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA316IDBVR | No shutdown pin; 100μA lower supply current (500μA); 10MHz GBW; 100μV VIO (typ) | Better DC precision and speed, but lacks shutdown - requires external enable circuitry for power gating. | Select when lowest possible offset and bandwidth are prioritized over integrated shutdown control. |
| MCP6001T-E/OT | Shut-down capable (1nA); 1MHz GBW; 200μV VIO (typ); 100μA supply current; no rail-to-rail output (clips ~80mV from rail) | Lower power and cost, but insufficient output swing for 3V ADC full-scale - requires gain adjustment or supply boost. | Select for ultra-low-power, non-critical swing applications where 1MHz bandwidth suffices and layout space is constrained. |
Compared with OPA316IDBVR and MCP6001T-E/OT, TLV2470IDBVT uniquely combines integrated shutdown, rail-to-rail I/O, and 2.8MHz bandwidth at 600μA - making it optimal for space-constrained, battery-operated systems requiring both precision and power-state control without external components.

FAQ
What is the maximum capacitive load the TLV2470IDBVT can drive without instability?
The TLV2470IDBVT remains stable with capacitive loads up to 1000pF when a series nulling resistor (RNULL ≥20Ω) is placed between the output and load. Without RNULL, instability may occur above ~10pF; Figure 42 in the TI datasheet (SLOS232E) confirms this design requirement for robust phase margin across temperature and supply voltage.
Does the TLV2470IDBVT support true rail-to-rail output swing at full rated load?
Yes - the TLV2470IDBVT delivers ±10mA output current while swinging to within 180mV of both VDD and GND rails at 3V supply, per Electrical Characteristics tables (page 4, VOH/VOL at IO = ±10mA). At lighter loads (e.g., 2.5mA), it achieves ≤150mV from rail, enabling full-scale signal capture in 3V ADC systems.
What logic levels activate and deactivate shutdown on the TLV2470IDBVT?
TLV2470IDBVT shutdown is activated when SHDN pin voltage is ≤0.8V (VIL), drawing 350nA/channel at 3V. It exits shutdown when SHDN rises to ≥2.0V (VIH). No external pull-up is needed - internal logic thresholds ensure clean transition across –40°C to +125°C, as specified in the Recommended Operating Conditions table (page 4).
How does input offset voltage drift with temperature for the TLV2470IDBVT?
The TLV2470IDBVT has a temperature coefficient of input offset voltage (αVIO) of 0.4μV/°C, meaning offset changes by ≤0.4μV per degree Celsius change. Over the full –40°C to +125°C range, this contributes ≤66μV additional drift beyond the 250μV room-temperature spec - critical for high-accuracy, wide-temperature industrial sensing.
Can the TLV2470IDBVT operate from a 2.7V supply while maintaining 2.8MHz gain-bandwidth?
Yes - the TLV2470IDBVT's gain-bandwidth product is characterized at 2.7V and remains 2.8MHz (typ) across the full 2.7–6V supply range, as shown in Figure 22 (Gain-Bandwidth Product vs Supply Voltage). This ensures consistent small-signal bandwidth in low-voltage battery systems without performance trade-offs.
