Product details
Overview
TLV2773CN from Texas Instruments is a dual-channel, rail-to-rail output CMOS operational amplifier optimized for single-supply operation (2.5 V to 5.5 V), delivering 10.5 V/µs slew rate, 5.1 MHz gain-bandwidth product, and 360 µV input offset voltage. It features micropower shutdown mode (<1 µA per channel), low 17 nV/√Hz input noise, and 2 pA input bias current - enabling high-precision signal conditioning in portable medical sensors and automotive analog front-ends.
For engineers reviewing the TLV2773CN datasheet, TLV2773CN pinout, TLV2773CN application, or TLV2773CN equivalent, this device is selected for low-voltage, low-noise, rail-to-rail output amplification where supply current ≤1 mA/channel and temperature stability across −40°C to 125°C are critical design requirements.
Technical Context
The TLV2773CN employs a CMOS input stage with differential pair topology, supporting rail-to-rail output swing via complementary push-pull output transistors. Its internal architecture enables stable unity-gain operation with 46° phase margin into 600-Ω loads and 100-pF capacitive loads.
It integrates independent shutdown control for each amplifier channel (pins 5 and 12), allowing dynamic power management without external circuitry. The device is characterized at both 2.7 V and 5 V supplies, with input common-mode range extending from GND to VDD −1.3 V and output swing within 100 mV of either rail under 2.2-mA load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 10.5 V/µs typ at VDD = 5 V - supports fast settling for 12-bit ADC driving with ≤0.01% error in <0.6 µs. |
| Gain-Bandwidth Product | 5.1 MHz typ - enables stable closed-loop gain ≥10 up to ~500 kHz with minimal peaking. |
| Input Offset Voltage | 360 µV max at 25°C - ensures ≤0.036% full-scale error in 10-V reference buffer applications. |
| Supply Current / Channel | 1 mA typ at VDD = 5 V - enables dual op-amp operation from coin-cell or Li-ion battery for >1-year portable life. |
| Rail-to-Rail Output | Swings within 100 mV of VDD and GND at 2.2-mA load - maximizes dynamic range when interfacing with 3.3-V or 5-V SAR ADCs. |
| Shutdown Current | 0.8–1.5 µA per channel - reduces system standby power by >99.9% versus active mode. |
| Input Noise Voltage | 17 nV/√Hz at 10 kHz - preserves SNR in sensor signal chains with bandwidths up to 100 kHz. |
Pinout & Package
TLV2773CN is housed in a 14-pin plastic DIP (dual in-line package) with 0.3-inch body width and standard through-hole mounting. Pin pitch is 0.1 inch (2.54 mm); lead finish is matte tin.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of Channel 1 - drives loads up to ±50 mA; rail-to-rail swing supports full-scale ADC input buffering. |
| 2 | 1IN− | Inverting input of Channel 1 - high-impedance CMOS node (10¹² Ω); sensitive to PCB leakage and EMI coupling. |
| 3 | 1IN+ | Non-inverting input of Channel 1 - matched to Pin 2 for optimal common-mode rejection in differential configurations. |
| 4 | VDD | Positive supply rail - accepts 2.5–5.5 V; bypass capacitor (0.1 µF) required at pin for stability. |
| 5 | 1SHDN | Active-low shutdown enable for Channel 1 - pulls to GND to disable; open or high = active. |
| 6 | 2IN+ | Non-inverting input of Channel 2 - electrically isolated from Channel 1 inputs; supports independent signal paths. |
| 7 | 2IN− | Inverting input of Channel 2 - identical electrical characteristics to Pin 2; enables dual instrumentation amp topologies. |
| 8 | GND | Analog ground reference - must be low-impedance star point; separate from digital ground in mixed-signal systems. |
| 9 | 2OUT | Output of Channel 2 - fully independent output stage; no crosstalk with Channel 1 above −80 dB at 10 kHz. |
| 10 | 2SHDN | Active-low shutdown enable for Channel 2 - independently controllable; allows asymmetric power gating. |
| 11 | NC | No internal connection - left unconnected; not used for thermal or mechanical reinforcement. |
| 12 | NC | No internal connection - floating; no routing or grounding required. |
| 13 | NC | No internal connection - unused pin; avoids solder bridging during wave soldering. |
| 14 | NC | No internal connection - mechanical placeholder; no electrical function. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2772CD | Same family, SOIC-8 package; no shutdown pins; 8-pin vs. 14-pin DIP; lower max temp (0°C to 70°C). | Board space-constrained consumer electronics; no need for per-channel shutdown control. | Select when footprint and cost are prioritized over extended temperature range and independent shutdown. |
| OPA2340UA | Single-supply, rail-to-rail I/O; 1 MHz GBW; 0.6 V/µs slew rate; 0.5 mV offset; no shutdown. | Lower-speed sensor interfaces where bandwidth <100 kHz suffices and shutdown is unnecessary. | Select when ultra-low input bias (0.2 pA) is critical and speed requirements are relaxed. |
Compared with TLV2772CD, TLV2773CN offers per-channel shutdown and extended temperature rating but requires larger PCB area; compared with OPA2340UA, it delivers 5× higher bandwidth and integrated shutdown at the cost of slightly higher offset voltage.

FAQ
What is the maximum operating temperature range for the TLV2773CN?
The TLV2773CN is rated for operation from −40°C to +125°C ambient temperature, validated per its 'I' suffix qualification. This makes it suitable for under-hood automotive applications and industrial environments where thermal stress exceeds commercial-grade limits. The device maintains specified slew rate, offset voltage, and supply current across this full range, as confirmed in the SLOS209G datasheet Section 6.
Does the TLV2773CN support true rail-to-rail input operation?
No, the TLV2773CN features rail-to-rail *output* only. Its input common-mode voltage range extends from GND to VDD −1.3 V (e.g., 0 V to 3.7 V at VDD = 5 V), as specified in the Recommended Operating Conditions table. It does not accept inputs at the positive rail - unlike rail-to-rail *input/output* amplifiers. This limitation must be considered when designing non-inverting configurations with high common-mode signals.
How much power does the TLV2773CN consume in shutdown mode?
In shutdown mode, the TLV2773CN draws 0.8–1.5 µA per channel (typical 1.0 µA), as measured at 25°C with VDD = 5 V. Both channels can be shut down simultaneously by pulling Pins 5 and 12 low, reducing total quiescent current to <3 µA - ideal for battery-backed systems requiring multi-year standby life. Full recovery time after shutdown release is 2.4 µs (t(ON)) per channel.
Can the TLV2773CN drive a 600-Ω load with low distortion?
Yes, the TLV2773CN is specifically characterized for 0.005% THD+N when driving a 600-Ω load at 1 kHz with AV = 1 and VDD = 5 V. This performance is enabled by its high slew rate (10.5 V/µs) and robust output stage, making it suitable for telecom line drivers and audio signal paths where harmonic distortion must remain below −86 dB.
What is the purpose of the NC pins on the TLV2773CN DIP package?
The TLV2773CN's 14-pin DIP package includes four NC (no-connect) pins - Pins 11, 12, 13, and 14 - which have no internal bond wires or silicon connections. These pins serve mechanical stability and standardization purposes only; they must remain unconnected and should not be grounded or routed. Their presence maintains pin compatibility with legacy 14-pin DIP footprints while accommodating the dual-amplifier + dual-shutdown architecture.
