Product details
Overview
TLV2454IDR from Texas Instruments is a quad rail-to-rail input/output operational amplifier optimized for ultralow-power, low-voltage portable systems. It delivers 220 kHz gain-bandwidth, 23 µA/channel supply current, ±10 mA output drive, 20 µV typical input offset voltage, and operates from 2.7 V to 6 V - enabling precision signal conditioning in battery-powered medical sensors and data acquisition front-ends.
For engineers reviewing the TLV2454IDR datasheet, TLV2454IDR pinout, TLV2454IDR application, or TLV2454IDR equivalent, this page provides verified electrical specifications, TSSOP-14 package layout, rail-to-rail dynamic range implications, shutdown behavior, and direct alternatives for low-power analog signal chain design.
Technical Context
The TLV2454IDR implements a CMOS input stage with rail-to-rail input common-mode range (0 V to VDD) and rail-to-rail output swing (within 250 mV of rails at 2.5 mA load), supporting full-scale operation in single-supply 3 V systems. Its 220 kHz gain-bandwidth product and 0.11 V/µs slew rate are specified at both 3 V and 5 V, with stable unity-gain performance up to 1000 pF capacitive load.
It features no internal shutdown control - unlike TLV2450/3/5 - and is rated for −40°C to 125°C industrial temperature operation. The device uses a fully differential input architecture with 10⁹ Ω differential input resistance and achieves 106 dB PSRR and 80 dB CMRR at DC, ensuring robustness against supply and common-mode noise in compact sensor interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 6 V - supports direct connection to Li-ion, 3.3 V, or dual 3 V coin-cell supplies without regulation. |
| Gain-Bandwidth Product | 220 kHz - enables stable amplification of DC–200 kHz signals (e.g., ECG, thermistor outputs) with minimal phase lag. |
| Supply Current per Channel | 23 µA - allows four independent amplifiers to operate continuously on <100 µA total, ideal for multi-sensor IoT nodes. |
| Input Offset Voltage (typ) | 20 µV - ensures <0.2 mV error in 100× gain stages, critical for high-resolution bridge sensor readouts. |
| Output Drive Capability | ±10 mA - drives 500 Ω loads directly (e.g., ADC reference buffers, LED biasing) without external gain stages. |
| Rail-to-Rail I/O | Yes - maximizes dynamic range in 3 V systems: inputs accept 0–3 V, outputs swing to within 250 mV of rails at 2.5 mA. |
| PSRR / CMRR | 106 dB / 80 dB - rejects power supply ripple and common-mode interference in noisy embedded environments. |
Pinout & Package
TSSOP-14 package: 4.4 mm × 5.0 mm body, 0.65 mm pitch, thin-profile surface-mount with exposed thermal pad (not electrically connected). Pin 1 marked by beveled edge or dot; pin numbering counterclockwise from top-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Amplifier A output - drives external load or feedback network; rail-to-rail capable. |
| 2 | 1IN− | Inverting input of Amp A - high-impedance CMOS node; connects to feedback resistor or sensor return. |
| 3 | 1IN+ | Non-inverting input of Amp A - accepts 0 V to VDD common-mode; used for sensor positive input. |
| 4 | GND | Analog ground reference - must be low-impedance star point for all four amplifiers' bias paths. |
| 5 | 4IN− | Inverting input of Amp D - isolated from other channels; enables independent differential configurations. |
| 6 | 4IN+ | Non-inverting input of Amp D - supports dedicated fourth sensor channel without crosstalk. |
| 7 | 4OUT | Amplifier D output - identical drive capability to Pin 1; usable for auxiliary signal path or redundancy. |
| 8 | VDD+ | Positive supply - powers all four op-amps; decoupling capacitor required within 5 mm. |
| 9 | 3OUT | Amplifier C output - shares same supply and ground as others; no internal isolation between channels. |
| 10 | 3IN− | Inverting input of Amp C - matches electrical characteristics of Pins 2 and 5; validated for matched gain networks. |
| 11 | 3IN+ | Non-inverting input of Amp C - identical input bias current (<5 nA) and offset specs as other inputs. |
| 12 | 2IN+ | Non-inverting input of Amp B - enables simultaneous 4-channel instrumentation amplifier front-end. |
| 13 | 2IN− | Inverting input of Amp B - low input capacitance (4.5 pF) minimizes high-frequency phase shift in filter designs. |
| 14 | 2OUT | Amplifier B output - fully rail-to-rail; tested for stability with 1000 pF capacitive load per channel. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2454CDR | Same silicon, 0°C to 70°C temperature grade; 23 µA/channel, 220 kHz GBW, TSSOP-14 package. | Restricted to commercial-temperature environments (e.g., consumer electronics, non-industrial test equipment). | Select TLV2454CDR only if operating ambient stays within 0–70°C and cost sensitivity outweighs extended temperature margin. |
| MCP6004-E/ST | Microchip quad RRIO op-amp: 1 µA/channel, 1 MHz GBW, 600 mV output swing headroom at 1 mA - higher speed but lower drive and wider output voltage gap. | Better for ultra-low-power wake-on-event sensing; unsuitable for driving 500 Ω loads or precision 3 V full-scale applications. | Choose MCP6004-E/ST when sub-µA quiescent current is mandatory and output swing requirements are relaxed. |
Compared with TLV2454CDR, the TLV2454IDR guarantees −40°C to 125°C operation and tighter initial offset (20 µV typ vs. 300 µV max over temp), while MCP6004-E/ST trades 23× lower supply current for 4.5× less output drive and 2.5× higher input-referred noise - making TLV2454IDR optimal for precision, wide-temp, moderate-speed analog front-ends.

FAQ
What is the operating temperature range for TLV2454IDR?
The TLV2454IDR is rated for −40°C to 125°C free-air temperature operation, validated across the full range for parameters including input offset voltage, supply current, and gain-bandwidth product. This makes TLV2454IDR suitable for under-hood automotive sensors, industrial control cabinets, and outdoor environmental monitoring where thermal extremes occur.
Does TLV2454IDR include a shutdown pin?
No, TLV2454IDR does not feature a shutdown pin. Unlike TLV2450, TLV2453, and TLV2455 variants, the TLV2454IDR lacks dedicated SHDN terminals. All four amplifiers remain active whenever VDD is applied. For power-gated applications, external FET switching of VDD or use of TLV2455IDR (which includes shutdown) is required.
What package type is used for TLV2454IDR?
TLV2454IDR is supplied in a 14-pin TSSOP (Thin Shrink Small Outline Package) with 0.65 mm lead pitch and 4.4 mm × 5.0 mm body dimensions. It is RoHS-compliant, lead-free, and designed for reflow soldering. The package includes an exposed thermal pad that is not electrically connected and may be left floating or grounded for mechanical stability.
Can TLV2454IDR drive capacitive loads?
Yes, TLV2454IDR is stable driving up to 1000 pF capacitive loads at unity gain, as confirmed by phase margin measurements (56°) in the datasheet. For loads exceeding 100 pF, a small series resistor (10–50 Ω) between output and capacitance is recommended to maintain stability in high-precision applications like anti-alias filtering.
What is the typical input offset voltage of TLV2454IDR?
The typical input offset voltage of TLV2454IDR is 20 µV at 25°C, with a maximum of 1300 µV over the full −40°C to 125°C temperature range. This low offset enables high-gain configurations (e.g., 100×) with sub-millivolt error budgets, critical for precision bridge sensor interfaces and medical-grade biopotential amplification using TLV2454IDR.
