Product details
Overview
TLV2461CP from Texas Instruments is a single-channel rail-to-rail input/output operational amplifier optimized for low-voltage portable systems. It delivers 6.4 MHz gain-bandwidth product, 1.6 V/µs slew rate, ±80 mA output drive, 500 µA/channel supply current, and 100 µV input offset voltage - enabling high-fidelity analog signal buffering in ADC front-ends and sensor interfaces.
For engineers reviewing the TLV2461CP datasheet, TLV2461CP pinout, TLV2461CP application, or TLV2461CP equivalent, key selection criteria include its rail-to-rail I/O swing at 2.7–6 V supply, micropower shutdown mode (0.3 µA/channel), −40°C to 125°C industrial temperature range, and compatibility with space-constrained DIP-8 packaging.
Technical Context
The TLV2461CP implements a CMOS input stage with rail-to-rail common-mode input range extending beyond supply rails, enabling full dynamic range utilization in 3 V and 5 V systems. Its output stage supports true rail-to-rail swing with high-current sourcing/sinking capability (±80 mA at 5 V), overcoming limitations of earlier rail-to-rail op amps.
It integrates a dedicated shutdown terminal (Pin 5) that places the amplifier in ultralow-power state (0.3 µA/channel) while forcing output into high-impedance mode. The device maintains DC precision (100 µV VIO, 11 nV/√Hz noise) and AC performance (6.4 MHz GBW, 1.6 V/µs SR) simultaneously under micropower operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 6 V single supply - supports direct interface with Li-ion batteries and 3.3 V/5 V logic without level-shifting. |
| Gain-Bandwidth Product | 6.4 MHz - enables stable unity-gain buffer configurations up to ~6 MHz with minimal phase margin degradation. |
| Slew Rate | 1.6 V/µs - supports clean 1 VPP signals up to ~250 kHz without slew-induced distortion. |
| Input Offset Voltage | 100 µV (typ) - ensures <0.01% gain error in 1 V full-scale precision sensor amplification. |
| Output Drive | ±80 mA (at 5 V) - drives 62 Ω loads directly, eliminating need for external buffers in DAC output stages. |
| Shutdown Current | 0.3 µA/channel - reduces system standby power by >99.9% versus active mode (500 µA). |
| Input Noise Voltage | 11 nV/√Hz @ 1 kHz - preserves SNR in low-level audio and instrumentation signal chains. |
Pinout & Package
TLV2461CP is housed in an 8-pin plastic DIP (P package) with 0.3-inch body width and through-hole mounting. Pin 1 is identified by a beveled edge or molded dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No internal connection - left unconnected per TI datasheet; no routing required. |
| 2 | IN− | Inverting input - accepts feedback network or differential signal source; high-impedance CMOS node. |
| 3 | IN+ | Non-inverting input - connects to reference, sensor, or signal source; rail-to-rail common-mode range (0 to VDD). |
| 4 | GND | Analog ground reference - must be low-impedance star point shared with ADC reference and power supply return. |
| 5 | SHDN | Active-high shutdown control - ≥2 V enables operation; ≤0.7 V disables amplifier and forces high-Z output. |
| 6 | VDD+ | Positive supply - accepts 2.7–6 V; decoupling capacitor (0.1 µF ceramic) required within 5 mm. |
| 7 | OUT | Amplifier output - rail-to-rail swing (within 10 mV of rails); capable of ±80 mA drive into resistive loads. |
| 8 | NC | No internal connection - electrically isolated; may be used as mechanical anchor or left floating. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full utilization of 3 V and 5 V supply rails - critical for maximizing ADC dynamic range in battery-powered systems. |
| Micropower shutdown mode | Reduces quiescent current to 0.3 µA/channel - extends battery life in intermittent-sampling applications like data loggers. |
| High output drive (±80 mA) | Drives heavy capacitive or resistive loads directly - eliminates external buffer stages in DAC output and line-driver circuits. |
| Low input offset voltage (100 µV) | Minimizes DC error in precision gain stages - suitable for strain gauge and thermopile amplifiers without trimming. |
| Wide temperature range (−40°C to 125°C) | Qualified for industrial and automotive under-hood environments - operates reliably across full specification range. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2461CD | Same electrical specs but in SOIC-8 package; 0°C to 70°C temp range vs. TLV2461CP's −40°C to 125°C. | Not qualified for extended industrial or automotive ambient conditions; unsuitable for high-reliability embedded control. | Select TLV2461CD only for commercial-grade cost-sensitive PCBs where temperature range is limited. |
| OPA344PA | Lower input offset (50 µV typ), higher GBW (1 MHz), but no shutdown pin and 1.8–5.5 V supply range. | Lacks power-gating capability; requires external enable circuitry for low-power sleep modes. | Choose OPA344PA when ultra-low offset dominates over shutdown functionality and temperature range is not critical. |
Compared with TLV2461CD and OPA344PA, the TLV2461CP uniquely combines extended temperature operation, integrated shutdown, and rail-to-rail I/O in a through-hole DIP package - making it the only option for legacy industrial designs requiring field-serviceable sockets and wide thermal margins.

FAQ
What is the operating temperature range of the TLV2461CP?
The TLV2461CP is rated for operation from −40°C to 125°C, meeting industrial and extended automotive requirements. This range is confirmed in the "Recommended Operating Conditions" table of the SLOS220J datasheet, where the "C suffix" designation corresponds to the P-package DIP variant. Its guaranteed performance across this span makes TLV2461CP suitable for under-hood automotive sensors and factory-floor PLC modules.
Does the TLV2461CP support rail-to-rail input and output operation?
Yes, the TLV2461CP provides true rail-to-rail input common-mode voltage range (0 V to VDD) and rail-to-rail output swing (within 10 mV of either rail). This is explicitly stated in the device description and verified in electrical characteristics tables showing VOH ≥ VDD − 0.1 V and VOL ≤ 0.1 V at 5 V supply. The feature enables maximum dynamic range in low-voltage 3 V and 5 V systems.
What is the function of Pin 5 (SHDN) on the TLV2461CP?
Pin 5 is the active-high shutdown control input. When driven to ≥2 V (relative to GND), the TLV2461CP operates normally; when pulled ≤0.7 V, it enters ultralow-power shutdown mode drawing just 0.3 µA per channel and placing the output in high-impedance state. This behavior is documented in both the "Recommended Operating Conditions" and "Electrical Characteristics" sections of the SLOS220J datasheet.
Can the TLV2461CP drive a 600 Ω load effectively?
Yes - the TLV2461CP delivers ±80 mA output current at 5 V supply, enabling it to drive a 600 Ω load with up to 48 VPP swing (I = V/R → 48 V / 600 Ω = 80 mA). Real-world performance is validated in Figures 5–8 of the datasheet, which show VOH/VOL curves sustaining >4.8 V and <0.2 V respectively at 10 mA load - well within 600 Ω capability at typical signal levels.
How does the TLV2461CP compare to the TLV2460CP in pin compatibility?
The TLV2461CP (single-channel) and TLV2460CP (single-channel with shutdown) share identical 8-pin DIP pinouts: Pin 2 = IN−, Pin 3 = IN+, Pin 4 = GND, Pin 5 = SHDN, Pin 6 = VDD+, Pin 7 = OUT. However, TLV2460CP has NC on Pins 1 and 8, while TLV2461CP also assigns NC to those pins - confirming full pin-for-pin compatibility in DIP-8 footprint. Both require same PCB layout.
