Product details
Overview
TLV2763IN from Texas Instruments is a dual-channel, micropower, rail-to-rail input/output operational amplifier with shutdown control, operating from 1.8 V to 3.6 V supply. It delivers 500 kHz bandwidth and 0.20 V/μs slew rate at only 20 μA per channel, with 550 μV input offset voltage and 10 nA shutdown current per channel - optimized for battery-powered sensor signal conditioning in industrial temperature range (−40°C to +85°C).
For engineers reviewing the TLV2763IN datasheet, TLV2763IN pinout, TLV2763IN application, or TLV2763IN equivalent, this device is selected for ultra-low-power analog front-ends where supply headroom is constrained (e.g., single-cell LiFePO₄ or two alkaline cells), shutdown sequencing is required, and rail-to-rail I/O swing at sub-2-V operation is critical.
Technical Context
The TLV2763IN implements CMOS input stage architecture enabling rail-to-rail common-mode input range (−0.2 V to VDD + 0.2 V) and rail-to-rail output swing within 25 mV of rails at 100 μA load. Its micropower design uses optimized biasing to maintain 500 kHz gain-bandwidth product across 1.8–3.6 V while limiting supply current to 20 μA/channel under active operation.
Shutdown functionality is implemented via dedicated SHDN pin with logic-compatible thresholds (VIH ≥ 2 V at VDD = 2.7–3.6 V; VIL ≤ 0.6 V), enabling fast enable/disable transitions (t(on) = 5 μs, t(off) = 0.8 μs) and reducing total supply current to 10 nA per channel in shutdown mode - essential for intermittent-sampling systems like portable gas sensors or wireless node wake-up amplifiers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 3.6 V - supports direct operation from two AA/AAA cells (end-of-life 1.8 V) or NiMH/NiCd (2.4 V nominal) |
| Supply Current (per channel) | 20 μA typical at 25°C - enables multi-year battery life in always-on low-frequency measurement circuits |
| Input Offset Voltage | 550 μV max at 25°C - ensures <1 mV error in 12-bit ADC front-end with gain ≤10 |
| Unity-Gain Bandwidth | 500 kHz - sufficient for anti-aliasing filtering and sensor signal amplification up to ~100 kHz |
| Shutdown Current (per channel) | 10 nA typical - reduces system standby power by >99.9% vs active mode, critical for duty-cycled IoT nodes |
| Rail-to-Rail I/O | Input range: −0.2 V to VDD + 0.2 V; Output swing: within 25 mV of rails at 100 μA - maximizes dynamic range at 1.8 V supply |
| Operating Temperature | −40°C to +85°C - qualified for industrial-grade embedded monitoring and control applications |
Pinout & Package
TLV2763IN is housed in an 8-pin plastic DIP (dual in-line package) with 0.3-inch body width and 0.1-inch lead pitch, suitable for through-hole prototyping and legacy industrial PCBs requiring mechanical robustness and thermal mass.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of Channel 1 - drives loads up to ±10 mA; rail-to-rail swing enables full utilization of 1.8 V supply |
| 2 | 1IN− | Inverting input of Channel 1 - high-impedance CMOS node (IIB = 3 pA typical); accepts signals down to −0.2 V |
| 3 | 1IN+ | Non-inverting input of Channel 1 - rail-to-rail common-mode range allows direct connection to resistive sensor bridges |
| 4 | GND | Analog ground reference - must be tied to low-impedance ground plane; separates signal return from power return |
| 5 | NC | No internal connection - left unconnected; no routing or grounding required |
| 6 | 1SHDN | Channel 1 shutdown control - active-high logic input; pulls supply current to 10 nA when driven low |
| 7 | VDD | Positive supply rail - accepts 1.8–3.6 V; requires local 0.1 μF ceramic + 6.8 μF tantalum decoupling |
| 8 | 2OUT | Output of Channel 2 - independent output; enables dual-path signal conditioning without cross-talk in shutdown |
Key Features
| Feature | Design Value |
|---|---|
| Micropower operation | 20 μA per channel enables >10-year battery life in 10-second wakeup interval sensor nodes |
| Dual independent shutdown | Separate SHDN pins per channel allow selective disabling - e.g., disable one op-amp during ADC conversion to reduce noise |
| Rail-to-rail input stage | −0.2 V to VDD + 0.2 V input range permits direct interfacing with 0–VDD sensor outputs without level-shifting |
| Low input bias current | 3 pA typical enables use with >1 MΩ feedback networks - critical for high-impedance pH or photodiode amplifiers |
| Stable with capacitive loads | Phase margin >63° with 100 pF load ensures stability in driving ADC input capacitors or long cables without external compensation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel micropower op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2763ID | Same electrical specs; MSOP-8 package (3 mm × 3 mm) instead of PDIP-8 - 75% smaller footprint, surface-mount only | Preferred for space-constrained PCBs; requires reflow assembly; thermal resistance ΘJA = 260°C/W vs 78°C/W for PDIP | Select TLV2763ID for volume production with automated SMT lines; TLV2763IN remains optimal for hand-soldered prototypes and ruggedized industrial modules. |
| LPV821DRX | Lower supply current (650 nA), lower bandwidth (10 kHz), no shutdown; rail-to-rail I/O; 1.6 V to 5.5 V supply | Better for nano-power always-on detection (e.g., tamper sensing); unsuitable for signal amplification above 10 kHz or shutdown-controlled systems | Choose LPV821DRX only when sub-μA quiescent current dominates over bandwidth and shutdown needs - not a functional replacement for TLV2763IN. |
Compared with TLV2763ID, TLV2763IN offers superior thermal dissipation and mechanical reliability in vibration-prone environments but requires larger board area; versus LPV821DRX, TLV2763IN provides 50× higher bandwidth and integrated shutdown - making it the sole choice for dual-channel, shutdown-capable, >100 kHz signal conditioning at 1.8 V.

FAQ
What is the maximum supply voltage rating for TLV2763IN?
The absolute maximum supply voltage for TLV2763IN is 4 V, but the recommended operating range is strictly 1.8 V to 3.6 V. Exceeding 3.6 V may cause parametric shift or accelerated aging; operation at 4 V is not guaranteed and voids TI's standard warranty. Designers should maintain VDD ≤ 3.6 V even during transient conditions.
Does TLV2763IN support true rail-to-rail output swing at 1.8 V supply?
Yes, TLV2763IN achieves rail-to-rail output swing at 1.8 V: VOH ≥ 1.77 V (within 30 mV of VDD) and VOL ≤ 25 mV (within 25 mV of GND) at 100 μA load and 25°C. This is confirmed in the Electrical Characteristics table (page 6) and enables full utilization of the 1.8 V supply in single-supply configurations.
How does the shutdown function behave on TLV2763IN?
TLV2763IN features independent shutdown control per channel via dedicated SHDN pins (Pin 6 for Channel 1, Pin 14 for Channel 2). When SHDN is pulled low (<0.6 V), that channel's supply current drops to 10 nA typical; when high (>2 V), the channel operates normally. Turn-on time is 5 μs, turn-off time is 0.8 μs - verified in Shutdown Characteristics (page 7).
Can TLV2763IN drive a 100 pF capacitive load without oscillation?
Yes, TLV2763IN maintains phase margin >63° with 100 pF capacitive load (Figure 18, page 11), ensuring stable unity-gain operation without external compensation. For loads >10 pF, TI recommends adding a 20 Ω series resistor (RNULL) between output and load - a proven layout technique documented in Application Information (page 14).
What is the input bias current specification for TLV2763IN?
TLV2763IN has a typical input bias current of 3 pA at 25°C, with a maximum of 200 pA across the full −40°C to +85°C industrial temperature range. This ultra-low IIB enables high-impedance sensor interfaces (e.g., thermistors, photodiodes) without significant DC error - specified in the Input Characteristics table (page 5).
