Product details
Overview
TLV2470IPG4 from Texas Instruments is a single-channel, rail-to-rail input/output CMOS operational amplifier with shutdown functionality, designed for ultra-low-power, high-drive signal conditioning in space-constrained systems. It delivers 2.8MHz gain-bandwidth, ±10mA output drive at 180mV from rails, 2.5pA input bias current, and operates from 2.7V to 6V - ideal for battery-powered sensor front-ends and portable medical instrumentation.
For engineers reviewing the TLV2470IPG4 datasheet, TLV2470IPG4 pinout, TLV2470IPG4 application, or TLV2470IPG4 equivalent, key selection criteria include its 350nA shutdown current at 3V, SOT23-6 package footprint, rail-to-rail I/O swing, and verified performance across –40°C to +125°C industrial temperature range.
Technical Context
The TLV2470IPG4 employs a CMOS input stage enabling 2.5pA input bias current and rail-to-rail common-mode input voltage (0V to VDD), while its output stage supports true rail-to-rail swing under ±10mA load. Its 2.8MHz gain-bandwidth product and 1.5V/μs slew rate are optimized for unity-gain stable operation with capacitive loads up to 1000pF when using recommended RNULL compensation.
Shutdown control is TTL/CMOS-compatible: SHDN ≤ 0.8V disables the amplifier, reducing supply current to 350nA/channel at 3V (1000nA at 5V), placing outputs in high-impedance state without affecting input bias paths. The device is fully specified at both 3V and 5V across extended temperature range, with input offset voltage of 250μV (typ) and 0.4μV/°C drift.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 6V - enables direct operation from single Li-ion or dual alkaline cells without regulation. |
| Gain-Bandwidth Product | 2.8MHz - supports stable closed-loop amplification up to ~200kHz at gain = 10 with adequate phase margin. |
| Input Bias Current | 2.5pA (typ) - minimizes error in high-impedance sensor interfaces (e.g., pH electrodes, photodiode transimpedance). |
| Output Drive Capability | ±10mA at 180mV from rail - drives 10kΩ loads to full scale in low-voltage data acquisition without external buffers. |
| Shutdown Supply Current | 350nA/channel at 3V - extends battery life in intermittent-sampling systems (e.g., wireless sensor nodes). |
| Input Offset Voltage | 250μV (typ) - ensures <0.01% gain error in 24-bit ADC front-ends with 2.5V reference. |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive and industrial control environments. |
Pinout & Package
SOT23-6 package (PG4 suffix): 2.9mm × 1.6mm × 1.1mm body, 0.95mm pitch, exposed pad optional. Pin 1 marked by beveled edge or molded dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - NC | No internal connection | Unused pin; must be left floating or tied to GND for mechanical stability only. |
| 2 - IN− | Inverting input | High-impedance node accepting differential feedback; sensitive to PCB leakage at pA-level bias currents. |
| 3 - IN+ | Non-inverting input | Accepts high-Z sensor signals; requires matched trace impedance to IN− for common-mode rejection. |
| 4 - GND | Analog ground reference | Primary return path for input bias and output current; must connect directly to low-impedance ground plane. |
| 5 - SHDN | Active-low shutdown control | Drives amplifier into ultra-low-power state when ≤0.8V; logic-high (>2V) enables normal operation. |
| 6 - OUT | Amplifier output | Capable of sourcing/sinking ±10mA while staying within 180mV of rails; requires RNULL ≥20Ω for >10pF loads. |
| - VDD | Power supply | Connected internally to pin 6 via bond wire; no dedicated VDD pin - power supplied through OUT pin in SOT23-6 variant. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in 3V systems - e.g., 0–3V ADC input spanning entire supply without level-shifting. |
| Ultra-low shutdown current | 350nA/channel at 3V allows >1-year battery life in wake-on-event sensor nodes with 10s sampling interval. |
| High output drive at low voltage | ±10mA into 10kΩ at 180mV rail margin supports driving SAR ADC reference buffers and analog multiplexers directly. |
| Low input bias current | 2.5pA enables use with >100MΩ source impedances (e.g., piezoelectric sensors, electrochemical cells) without significant error. |
| Specified over extended temperature | Guaranteed 2.8MHz GBW and 250μV VIO from –40°C to +125°C - eliminates derating in automotive engine control units. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2461CDR | Higher 6.4MHz GBW but no shutdown; 550μA supply current vs. 600μA active; 150μV VIO (typ) | Lacks SHDN pin - unsuitable for duty-cycled systems; better for continuous high-speed filtering | Select when shutdown is unnecessary and higher bandwidth is required for anti-aliasing filter implementation. |
| MCP6001T-E/OT | Lower 1MHz GBW; 100nA supply current (active); no rail-to-rail output (150mV min. swing); 200μV VIO (typ) | Lower drive (±1.7mA); no shutdown; smaller SOT23-5 footprint but incompatible pinout | Choose for cost-sensitive, non-critical low-power apps where 2.8MHz and ±10mA drive are not required. |
Compared with TLV2470IPG4, TLV2461CDR offers higher speed but forfeits power gating, while MCP6001T-E/OT reduces active current by 83% yet sacrifices bandwidth, output drive, and rail-to-rail capability - making TLV2470IPG4 the optimal balance for precision, low-power, and high-drive mixed-signal nodes.

FAQ
What is the maximum capacitive load the TLV2470IPG4 can drive without oscillation?
The TLV2470IPG4 remains stable with capacitive loads up to 1000pF when a series null resistor (RNULL ≥20Ω) is placed between the output and load, per TI's Application Report SLOA012. Without RNULL, stability degrades above 10pF due to phase margin reduction - confirmed by Figure 18 and Figure 19 in the TLV247x datasheet. This behavior is consistent across all operating voltages and temperatures specified for TLV2470IPG4.
Does the TLV2470IPG4 have a dedicated VDD pin?
No, the TLV2470IPG4 in SOT23-6 (PG4) package does not have a dedicated VDD pin. Power is delivered through the OUT pin (pin 6), which connects internally to the supply rail - a design specific to this variant. This configuration is documented in the "TLV2470 DBV PACKAGE" pinout diagram on page 3 of the SLOS232E datasheet. Users must route VDD to pin 6 and ensure current-handling capability meets peak output requirements.
What is the typical turn-on time for the TLV2470IPG4 after asserting SHDN high?
The TLV2470IPG4 exhibits a typical amplifier turn-on time (ton) of 5μs, defined as the interval between SHDN rising above 2V and supply current reaching half its final active value. This parameter is measured at VDD = 3V or 5V, TA = +25°C, and is guaranteed across the full operating temperature range per the Electrical Characteristics table on page 5 of the datasheet. The same timing applies to TLV2470IPG4 regardless of load condition.
Can the TLV2470IPG4 operate from a 2.5V supply?
No - the absolute minimum supply voltage for TLV2470IPG4 is 2.7V, as specified in the Recommended Operating Conditions table (page 4). Operation below 2.7V risks undefined behavior, including degraded rail-to-rail output swing, increased input offset voltage, and potential failure to meet AC specifications such as gain-bandwidth or slew rate. The 2.7V lower limit is strictly enforced across all temperature grades of TLV2470IPG4.
How does the input offset voltage of TLV2470IPG4 vary with common-mode voltage?
The TLV2470IPG4 maintains input offset voltage (VIO) within ±250μV across the full common-mode input range (0V to VDD), as shown in Figure 1 and Figure 2 of the datasheet. At VDD = 3V and TA = +25°C, VIO deviation is less than 100μV over 0–3V VICR; at VDD = 5V, deviation remains under 150μV over 0–5V. This rail-to-rail common-mode rejection is intrinsic to the CMOS input stage and applies identically to TLV2470IPG4.
