Product details
Overview
TLV2455CN 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, ±10 mA output drive, 23 µA/channel supply current, and operates from 2.7 V to 6 V - enabling high-precision signal conditioning in battery-powered medical sensors and data acquisition front-ends.
For engineers reviewing the TLV2455CN datasheet, TLV2455CN pinout, TLV2455CN application, or TLV2455CN equivalent, key selection criteria include its shutdown capability (16 nA/channel), rail-to-rail I/O swing at 3 V, 106 dB PSRR, and TSSOP-16 packaging - all critical for space-constrained, single-supply analog signal chains.
Technical Context
The TLV2455CN integrates four independent amplifiers with individual shutdown control per pair (pins 1/2SHDN and 3/4SHDN), supporting selective channel power gating. Its rail-to-rail input stage uses complementary differential pairs, while the output stage employs Class AB architecture to sustain ±10 mA into loads while maintaining linearity near supply rails.
It is fully specified across −40°C to 125°C and supports stable operation with capacitive loads up to 1000 pF (56° phase margin). Shutdown logic is CMOS-compatible: applying <0.5 V (at 3 V supply) or <0.8 V (at 5 V supply) to SHDN pins places outputs in high-impedance state and reduces quiescent current to 16 nA/channel.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 6 V - enables direct interface with Li-ion, 3.3 V, and 5 V rails without level-shifting. |
| Gain-Bandwidth Product | 220 kHz - supports DC-coupled sensor amplification and low-frequency filtering up to ~20 kHz with unity-gain stability. |
| Supply Current per Channel | 23 µA - allows continuous operation for years on coin-cell batteries in always-on monitoring nodes. |
| Output Drive Capability | ±10 mA - drives 10 kΩ loads to within 150 mV of rails, sufficient for driving ADC reference buffers and active filters. |
| Input Offset Voltage | 20 µV (typ) - ensures sub-1 LSB error in 16-bit systems with 5 V full-scale range. |
| Power Supply Rejection Ratio | 106 dB - rejects ripple and noise from noisy switching regulators in mixed-signal PCBs. |
| Shutdown Current per Channel | 16 nA - reduces total system standby power to nanoampere levels during sleep modes. |
Pinout & Package
TSSOP-16 package with 0.65 mm pitch, 5.0 mm × 4.4 mm body, and exposed thermal pad (not electrically connected). RoHS-compliant, lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT, 2OUT, 3OUT, 4OUT | Amplifier output terminals | Each drives ±10 mA; rail-to-rail swing supports full dynamic range in 3 V systems. |
| 1IN−, 2IN−, 3IN−, 4IN− | Inverting inputs | High-impedance (10⁹ Ω), support precision transducer interfaces with minimal loading. |
| 1IN+, 2IN+, 3IN+, 4IN+ | Non-inverting inputs | Rail-to-rail common-mode range (0 V to VDD) enables direct connection to resistive sensor bridges. |
| GND | Analog ground reference | Single ground pin shared by all four amplifiers; requires low-impedance local decoupling. |
| VDD+ | Positive supply | Accepts 2.7–6 V; PSRR of 106 dB minimizes supply noise coupling into signal path. |
| 1/2SHDN | Shutdown control for Amps 1 & 2 | CMOS-input logic: <0.5 V (3 V supply) disables Amps 1/2; outputs go high-Z. |
| 3/4SHDN | Shutdown control for Amps 3 & 4 | Independent control enables staggered wake-up or dual-channel power management. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full utilization of 3 V supply range - e.g., 0–3 V output swing for 12-bit SAR ADC drivers. |
| Ultralow 23 µA/channel supply current | Permits integration of four precision op-amps in wearable ECG front-ends without compromising battery life. |
| 16 nA/channel shutdown current | Reduces idle power by >1400× versus active mode - essential for duty-cycled sensor nodes. |
| 220 kHz gain-bandwidth at 23 µA | Outperforms competing micropower op-amps (e.g., TLC27L4) by >2× bandwidth per µA consumed. |
| Specified from −40°C to 125°C | Validates performance in automotive cabin modules and industrial process controllers without derating. |

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 |
|---|---|---|---|
| TLV2474IPW | Higher supply current (600 µA/ch), 2.8 MHz GBW, no shutdown | Used where speed >200 kHz is required; unsuitable for battery life-critical designs | Select when bandwidth >1 MHz is needed and power budget allows >25× higher current |
| LPV821RGTR | Lower supply current (650 nA/ch), 6.5 kHz GBW, rail-to-rail input only | Targeted at ultra-low-power nanopower sensing; insufficient drive for ADC buffering | Choose for sub-µA always-on monitoring where output drive and bandwidth are secondary |
Compared with TLV2455CN, TLV2474IPW trades 26× higher power for 13× more bandwidth and no power management, while LPV821RGTR reduces current by 35× but sacrifices 34× bandwidth and lacks rail-to-rail output - making TLV2455CN the optimal balance for precision, low-power, multi-channel signal chains.

FAQ
What is the operating temperature range for TLV2455CN?
The TLV2455CN is rated for operation from −40°C to 125°C, meeting industrial and automotive under-hood requirements. This range is validated across all electrical specifications including input offset voltage, PSRR, and output drive - ensuring reliability in harsh environments without derating.
Does TLV2455CN support true rail-to-rail output swing under load?
Yes, TLV2455CN delivers rail-to-rail output swing into 2.5 mA loads, reaching within 150 mV of each rail at 3 V supply. At 5 V, it swings to within 70 mV of rails. This is confirmed in the datasheet's VOL/VOH specifications under loaded conditions (IOL = 500 µA, IOH = −500 µA).
How does the shutdown function work on TLV2455CN?
TLV2455CN features two independent shutdown pins: 1/2SHDN controls amplifiers 1 and 2, while 3/4SHDN controls amplifiers 3 and 4. Driving either pin below 0.5 V (at 3 V supply) places the corresponding outputs in high-impedance state and reduces supply current to 16 nA per channel - verified in the IDD(SHDN) specification table.
What package type is TLV2455CN supplied in?
TLV2455CN is supplied in a 16-pin TSSOP package (PW suffix), with 0.65 mm lead pitch and 5.0 mm × 4.4 mm body dimensions. This surface-mount package supports automated assembly and provides thermal performance suitable for industrial ambient temperatures up to 125°C.
Can TLV2455CN operate from a single 3 V supply?
Yes, TLV2455CN is fully specified for single-supply operation from 2.7 V to 6 V. At 3 V, it maintains 220 kHz gain-bandwidth, 23 µA/channel supply current, and rail-to-rail input/output functionality - enabling direct use with Li-ion or coin-cell sources without voltage boosting.
