Product details
Overview
TLV2470CDBVT from Texas Instruments is a single-channel, rail-to-rail input/output CMOS operational amplifier with shutdown functionality in a 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 sensor signal conditioning in battery-operated medical and portable instrumentation.
For engineers reviewing the TLV2470CDBVT datasheet, TLV2470CDBVT pinout, TLV2470CDBVT application, or TLV2470CDBVT equivalent, key selection criteria include its 3V–6V supply range, 350nA shutdown current at 3V, rail-to-rail I/O swing, and SOT-23-6 footprint compatibility with space-constrained analog front-ends.
Technical Context
The TLV2470CDBVT 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 under load: ±10mA at 180mV from each rail and ±35mA at 500mV off-rail, making it suitable for driving ADC reference buffers and transducer interfaces without external level-shifting.
Shutdown control is implemented via a dedicated SHDN pin requiring VIH ≥ 2V and VIL ≤ 0.8V relative to GND. During shutdown, outputs enter high-impedance state and per-channel supply current drops to 350nA at 3V (1000nA at 5V), preserving battery life while maintaining fast turn-on/turn-off times of 5μs and 250ns respectively.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 6V - operates from single Li-ion cell (3.0V nominal) up to dual AA (3.2V) or regulated 5V systems. |
| Gain-Bandwidth Product | 2.8MHz - supports stable closed-loop gain ≥10 at 280kHz, sufficient for anti-aliasing filters and sensor amplification. |
| Input Offset Voltage | 250μV (typ) - enables <0.01% error in 2.5V full-scale 12-bit ADC interfaces without trimming. |
| Output Drive Capability | ±10mA at 180mV from rail - drives 10kΩ loads to within 180mV of supply, critical for rail-sensing applications. |
| Shutdown Supply Current | 350nA/ch at 3V - draws <1μA total in shutdown, extending shelf life of battery-powered devices by years. |
| Slew Rate | 1.5V/μs (typ at 5V) - settles 2V step in <1.8μs (0.01%), supporting moderate-speed data acquisition. |
| Input Bias Current | 2.5pA (typ) - minimizes voltage error across high-impedance sources like pH electrodes or photodiode TIA feedback networks. |
Pinout & Package

| 3 (IN+) | Non-inverting input | Full rail-to-rail common-mode range (0V to VDD); supports direct connection to grounded sensors. |
| 4 (GND) | Analog ground reference | Return path for input bias currents and output load; must be low-impedance to minimize noise coupling. |
| 5 (SHDN) | Active-low shutdown control | Logic-compatible input; pulls amplifier into ultra-low-power state when driven ≤0.8V (350nA IDD). |
| 6 (VDD) | Positive supply | Accepts 2.7V–6V; internal regulation ensures stable operation across battery discharge curve. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2460CDBVR | Higher 6.4MHz GBW but no shutdown; 550μA IQ; SOT-23-6 package. | Lacks shutdown function - unsuitable for duty-cycled sensor nodes requiring nanoampere standby. | Select when higher bandwidth is required and continuous operation is acceptable. |
| MCP6001T-E/OT | 1MHz GBW, 100μA IQ, no shutdown; SOT-23-5 package (no SHDN pin). | Lower power but no rail-to-rail output drive near rails - cannot deliver ±10mA at 180mV from rail. | Select for ultra-low-power applications where bandwidth and output swing requirements are relaxed. |
Compared with TLV2470CDBVT, TLV2460CDBVR offers higher speed but forfeits shutdown capability essential for battery longevity, while MCP6001T-E/OT achieves lower quiescent current at the cost of bandwidth and rail-to-rail output performance - making TLV2470CDBVT the optimal balance for precision, low-power, and shutdown-enabled designs.

FAQ
What is the maximum supply voltage for TLV2470CDBVT?
The absolute maximum supply voltage for TLV2470CDBVT is 7V, but the recommended operating range is 2.7V to 6V. Operation above 6V risks exceeding safe dissipation limits in the SOT-23-6 package and may degrade long-term reliability. TI specifies full electrical performance only within the 2.7V–6V range, including input common-mode range, output swing, and distortion metrics.
Does TLV2470CDBVT support true rail-to-rail output swing under load?
Yes, TLV2470CDBVT delivers true rail-to-rail output swing: it can source and sink ±10mA while remaining within 180mV of either rail, and ±35mA within 500mV of the rail. This is verified across the full 2.7V–6V supply range and specified in the Electrical Characteristics tables for both 3V and 5V operation - enabling direct interfacing with low-voltage ADCs and reference buffers without external level-shifting circuitry.
How does the shutdown function behave on TLV2470CDBVT?
When the SHDN pin is driven low (≤0.8V), TLV2470CDBVT disables the amplifier core and places the output in high-impedance state, reducing supply current to 350nA per channel at 3V (1000nA at 5V). Turn-on time is 5μs and turn-off time is 250ns, measured from SHDN logic transition to 50% of final IDD. The output remains high-Z during transition, preventing glitches on shared bus lines.
Can TLV2470CDBVT drive capacitive loads?
TLV2470CDBVT can drive capacitive loads up to 10pF stably in unity-gain configuration. For larger loads (e.g., ADC input capacitance >10pF), TI recommends adding a series null resistor (RNULL ≥20Ω) between the output and load to maintain phase margin >60° and prevent ringing. This is documented in Figure 42 of the datasheet and validated across temperature and supply voltage ranges.
What is the input offset voltage drift over temperature for TLV2470CDBVT?
The TLV2470CDBVT has a temperature coefficient of input offset voltage (αVIO) of 0.4μV/°C (typical), meaning offset drift is bounded by ±0.4μV per °C change from room temperature. Over the full operating range (0°C to +70°C), this contributes ≤28μV additional drift beyond the 250μV typical room-temperature offset - ensuring stable DC accuracy in thermally varying environments like handheld medical devices.
