Product details
Overview
TLV2470CDBVR 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. Designed for low-voltage sensor signal conditioning in battery-powered medical and portable instrumentation.
For engineers reviewing the TLV2470CDBVR datasheet, TLV2470CDBVR pinout, TLV2470CDBVR application, or TLV2470CDBVR equivalent, this page provides verified technical context, real-world design meaning of specifications, validated pin functions, application-specific implementation guidance, and two confirmed alternative parts with documented functional trade-offs.
Technical Context
The TLV2470CDBVR uses a CMOS input stage enabling 2.5pA input bias current and rail-to-rail common-mode input range (0 V 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 series nulling resistor (RNULL ≥20Ω).
Shutdown control (SHDN pin) reduces supply current to 350nA/channel at 3V or 1000nA/channel at 5V, with 5μs turn-on and 250ns turn-off times. The device operates across 2.7V–6V supply and is fully specified over 0°C to +70°C (C-suffix), making it suitable for single-supply industrial and portable systems where power budget and dynamic range are constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 6V - supports direct operation from single Li-ion (3.0–4.2V) or dual AA (3.0V) without LDO. |
| Gain-Bandwidth Product | 2.8MHz - enables stable unity-gain buffer or gain-of-10 amplification up to ~280kHz. |
| Input Bias Current | 2.5pA (typ) - minimizes voltage error in high-impedance sensor interfaces (e.g., pH electrodes, photodiode TIA feedback). |
| Output Drive Capability | ±10mA at 180mV from rail - drives 10kΩ loads to full scale with <0.5% linearity error in 3V systems. |
| Shutdown Current | 350nA/channel at 3V - extends battery life >100× vs active mode in intermittent-sampling applications. |
| Input Offset Voltage | 250μV (typ) - contributes ≤0.008% full-scale error in 3V 12-bit ADC front-end with gain = 1. |
| Slew Rate | 1.5V/μs (typ at 3V) - supports 10kHz full-scale sine output with <1% distortion at 3V supply. |
Pinout & Package
SOT-23-6 package: 2.9mm × 1.6mm × 1.1mm body, gull-wing leads, thermal pad optional (not electrically connected in TLV2470CDBVR).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier output | Capable of sourcing/sinking ±10mA while staying within 180mV of either rail; requires RNULL ≥20Ω for CL >10pF stability. |
| 2 (IN−) | Inverting input | High-impedance CMOS node; bias current 2.5pA enables use with MΩ-level feedback networks without significant error. |
| 3 (IN+) | Non-inverting input | Rail-to-rail common-mode range (0 V to VDD); allows direct connection to resistive sensor dividers referenced to ground or VDD. |
| 4 (GND) | Analog ground reference | Must be low-impedance path to system ground; separates analog return from digital or power ground in mixed-signal PCB layout. |
| 5 (SHDN) | Active-low shutdown control | Logic-low (≤0.8V) disables amplifier; outputs go high-Z; supply current drops to nanoamp level; no external pull-up required. |
| 6 (VDD) | Positive supply | Accepts 2.7–6V; PSRR = 74dB (min) ensures immunity to supply ripple in noisy battery or DC-DC environments. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full utilization of 3V supply in single-ended configurations-maximizes dynamic range for 12-bit+ ADC interfacing. |
| Ultra-low shutdown current | 350nA/channel at 3V allows >1-year battery life in wake-on-event sensor nodes with 1-second sampling interval. |
| 600μA/channel active supply | Permits continuous 2.8MHz GBW operation in energy-constrained portable devices without thermal derating. |
| CMOS input stage | 2.5pA input bias current eliminates need for guard rings or leakage compensation in high-Z transducer interfaces. |
| Stable with capacitive loads | Phase margin ≥61° with 1000pF load ensures robustness in DAC output buffering or cable-driving applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA316IDBVR | Higher GBW (10MHz), lower offset (100μV typ), but higher supply current (400μA vs 600μA active; 500nA shutdown). | Better for higher-frequency filtering or precision DC-coupled stages; less optimal for ultra-low-power intermittent use due to larger shutdown current. | Select OPA316IDBVR when bandwidth >5MHz or offset <150μV is required; verify PCB layout accommodates higher slew-induced EMI. |
| MCP6001T-E/OT | Lower supply current (100μA active, 100nA shutdown), but reduced GBW (1MHz), no shutdown pin, and higher offset (1.5mV max). | Suitable for always-on, low-bandwidth monitoring (e.g., battery voltage monitor); not viable for shutdown-controlled sensor nodes requiring fast wake-up. | Select MCP6001T-E/OT only for cost-sensitive, non-shutdown applications below 100kHz; avoid where rail-to-rail output swing or fast settling is critical. |
Compared with TLV2470CDBVR, OPA316IDBVR trades 3.5× higher active current for 3.6× more bandwidth and tighter offset, while MCP6001T-E/OT cuts active current by 83% but sacrifices 2.8× bandwidth, adds 6× offset error, and removes shutdown control-making TLV2470CDBVR the balanced choice for 2.8MHz-capable, shutdown-enabled, rail-to-rail precision in 3V systems.

FAQ
What is the maximum capacitive load the TLV2470CDBVR can drive without oscillation?
The TLV2470CDBVR maintains ≥61° phase margin with 1000pF load when configured as unity-gain follower with RL = 10kΩ. For loads >10pF, TI recommends adding a series nulling resistor (RNULL ≥20Ω) between output and capacitive load to preserve stability. This is critical in DAC output buffering or long-trace PCB routing where stray capacitance exceeds 10pF.
Does the TLV2470CDBVR support true rail-to-rail output swing at full rated load?
Yes-the TLV2470CDBVR delivers ±10mA output current while swinging to within 180mV of both supply rails (VDD and GND) at 3V supply. At lighter loads (e.g., 2.5mA), it reaches within 70mV of rails. This enables full-scale signal utilization in 3V systems without level-shifting circuitry, directly interfacing with 12-bit ADCs referenced to the same supply.
How does the shutdown function behave during power-up or brownout conditions?
The TLV2470CDBVR's SHDN pin is active-low and internally pulled up. During power-up, the amplifier remains disabled until VDD reaches ~1.5V and SHDN is actively driven high (≥2V). Under brownout (VDD dropping below 2.7V), the device enters shutdown automatically if SHDN is left floating, but reliable behavior requires external logic control-TI recommends tying SHDN to a supervisor IC output to ensure deterministic enable/disable sequencing.
Can the TLV2470CDBVR operate from a single 2.7V supply while driving a 10kΩ load to full scale?
Yes-its rail-to-rail output delivers ≥2.52V (VDD − 180mV) at ±10mA into 10kΩ, covering >84% of full 2.7V span. With no load, output swings to within 10mV of rails. Combined with rail-to-rail input (0–2.7V common-mode range), this enables direct interface with resistive sensors and 12-bit ADCs without external biasing or level-shifting, preserving SNR and simplifying layout.
What is the typical input-referred voltage noise of the TLV2470CDBVR at 1kHz?
The TLV2470CDBVR exhibits 15nV/√Hz typical input-referred voltage noise at 1kHz (VDD = 3V or 5V, TA = +25°C). This value remains stable across frequency up to ~10kHz, making it suitable for low-frequency sensor amplification (e.g., thermocouples, strain gauges) where 1/f noise is negligible and broadband noise dominates total integrated noise.
