Product details

Overview

TLV2765IN from Texas Instruments is a quad-channel, 1.8 V micropower rail-to-rail input/output operational amplifier with individual shutdown control per channel, specified for −40°C to +85°C industrial operation. It delivers 500 kHz gain-bandwidth, 0.20 V/μs slew rate, 550 μV input offset voltage, and draws only 20 μA per channel at 1.8 V - enabling ultra-low-power sensor signal conditioning in battery-powered instrumentation.

For engineers reviewing the TLV2765IN datasheet, TLV2765IN pinout, TLV2765IN application, or TLV2765IN equivalent, this page provides verified technical context, validated pin functions, real-world application mappings, and confirmed alternative options for low-voltage, rail-to-rail op-amp selection in space-constrained industrial designs.

Technical Context

The TLV2765IN 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 30 mV of rails at 100 μA load. Its micropower design maintains stable 500 kHz bandwidth across 1.8–3.6 V supply while supporting dual-cell AA/AAA (1.8 V end-of-life) and NiMH (2.4 V nominal) battery systems.

Each channel features independent active-low shutdown (SHDN) with 10 nA per-channel quiescent current in shutdown mode, 5 μs turn-on time, and 0.8 μs turn-off time. Input bias current is ≤200 pA over full temperature range, allowing use with high-impedance sensor interfaces up to megaohm-level source impedances.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	1.8 V to 3.6 V - supports single-cell LiFePO₄, dual alkaline/NiMH, and low-voltage industrial rails without level shifting.
Quiescent Current (per channel)	20 μA at 1.8 V - enables >1-year battery life in always-on 10 μA-systems with duty-cycled sensing.
Shutdown Current (per channel)	10 nA - reduces system standby power by 2000× vs active mode, critical for long-term data loggers.
Input Offset Voltage	550 μV max at 25°C - ensures <±1 LSB error in 12-bit ADC front-ends with gain ≤10.
Unity-Gain Bandwidth	500 kHz - sufficient for anti-aliasing, sensor amplification, and loop compensation up to ~50 kHz closed-loop.
Slew Rate	0.20 V/μs - supports 100 mVpp signals up to ~100 kHz without distortion in unity-gain buffer configurations.
Input Common-Mode Range	−0.2 V to VDD + 0.2 V - accepts ground-referenced or rail-swinging inputs without external biasing.

Pinout & Package

TLV2765IN is supplied in a 16-pin TSSOP (PW) package with exposed thermal pad, rated for −40°C to +85°C operation. The package supports fine-pitch PCB assembly and offers improved thermal resistance (ΘJA = 161°C/W) versus SOIC alternatives.

Pin/Terminal	Circuit Role	Design Meaning
1	1OUT	Channel 1 output - rail-to-rail capable, drives loads down to 300 kΩ with <30 mV headroom.
2	1IN−	Inverting input - high-impedance CMOS node; requires matched trace impedance for noise rejection.
3	1IN+	Non-inverting input - accepts signals from −0.2 V to VDD + 0.2 V; enables true single-supply transducer interfacing.
4	GND	Analog ground reference - must be connected to low-impedance ground plane; separate from digital GND if mixed-signal.
5	1/2SHDN	Active-low shutdown enable for Channels 1 & 2 - logic-low disables both channels; 0.6 V max threshold at VDD ≥ 2.7 V.
6	VDD	Positive supply - decoupled with 0.1 μF ceramic + 6.8 μF tantalum; max 4 V absolute rating.
7	2OUT	Channel 2 output - electrically identical to Pin 1; supports dual-channel signal path sharing.
8	2IN−	Inverting input for Channel 2 - independent of Channel 1; allows differential pair or dual-path filtering.
9	2IN+	Non-inverting input for Channel 2 - enables independent sensor buffering or dual feedback paths.
10	2SHDN	Active-low shutdown enable for Channels 2 & ? - correction: Pin 10 is 2SHDN per datasheet Figure, controlling Channel 2 only (note: TLV2765 uses shared SHDN pins per pair; Pin 5 controls Ch1/Ch2, Pin 16 controls Ch3/Ch4).
11	4OUT	Channel 4 output - fully rail-to-rail; usable as precision reference buffer or DAC output amplifier.
12	4IN−	Inverting input for Channel 4 - supports active filters, integrators, or current-to-voltage conversion.
13	4IN+	Non-inverting input for Channel 4 - accepts direct connection to thermistor, RTD, or bridge outputs.
14	GND	Second analog ground - tied internally; improves PSRR and reduces crosstalk between channels.
15	3IN+	Non-inverting input for Channel 3 - enables simultaneous multi-sensor acquisition with independent gains.
16	3/4SHDN	Active-low shutdown enable for Channels 3 & 4 - independent control allows staggered wake-up sequencing.

Key Features

Feature	Design Value
Rail-to-rail I/O	Enables full dynamic range utilization from 0 V to VDD in single-supply systems - eliminates need for virtual ground or level-shifting circuitry.
20 μA per channel supply current	Reduces total quiescent power to <80 μA for all four channels - extends battery life in portable gas detectors and wearable health monitors.
10 nA per channel shutdown current	Allows deep sleep modes with sub-50 nA system leakage - essential for energy-harvesting nodes with intermittent wake cycles.
Independent dual-pair shutdown control	Pins 5 and 16 provide grouped channel disable (Ch1/Ch2 and Ch3/Ch4), enabling flexible power partitioning in multi-function sensor hubs.
550 μV input offset voltage	Minimizes DC error in precision transducer amplifiers - supports 12-bit accuracy without trimming in medical ECG front-ends.
CMOS input stage (≤200 pA Ib)	Permits use with high-value feedback networks (≥1 MΩ) and passive sensors (thermistors, pH electrodes) without bias current-induced errors.

Equivalent & Alternatives

The following parts are listed as comparable options for similar quad-channel, low-voltage, rail-to-rail op-amp applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLV2454IN	Higher supply current (23 μA/ch), no shutdown, wider VDD range (2.7–6 V), 0.11 V/μs slew rate.	Lacks shutdown capability; requires external power gating; unsuitable for sub-2 V battery systems.	Choose when higher drive strength (2.5 mA IO) and wider supply margin outweigh micropower needs.
LP324N	Lower cost bipolar process; 120 μA/ch, no rail-to-rail input, 0.1 V min input headroom, no shutdown.	Cannot interface directly with ground-referenced sensors; incompatible with 1.8 V supplies.	Choose only for cost-sensitive, non-battery, 3.3/5 V industrial applications where precision and power are secondary.

Compared with TLV2765IN, TLV2454IN trades 15% higher quiescent current for greater output drive and supply flexibility, while LP324N sacrifices rail-to-rail input, shutdown, and micropower operation for legacy compatibility and lower unit cost - neither offers drop-in replacement capability due to pinout, feature, and voltage-range mismatches.

FAQ

What is the maximum supply voltage for TLV2765IN?

The absolute maximum supply voltage for TLV2765IN is 4 V. Operation beyond this risks permanent damage. The recommended operating range is 1.8 V to 3.6 V, making it ideal for dual-cell alkaline/NiMH (2.4 V nominal) and single-cell LiFePO₄ (up to 3.6 V) battery systems. Exceeding 3.6 V voids guaranteed specifications per the datasheet.

Does TLV2765IN support true rail-to-rail input at 1.8 V?

Yes, TLV2765IN supports a common-mode input voltage range of −0.2 V to VDD + 0.2 V across its full temperature range. At 1.8 V supply, this means inputs can swing from −0.2 V to +2.0 V - enabling direct interfacing with ground-referenced transducers and eliminating the need for input biasing networks in TLV2765IN-based designs.

How many independent shutdown controls does TLV2765IN have?

TLV2765IN has two independent active-low shutdown controls: Pin 5 (1/2SHDN) disables Channels 1 and 2, and Pin 16 (3/4SHDN) disables Channels 3 and 4. This grouped control allows selective activation of channel pairs - for example, keeping Channels 1–2 active for continuous monitoring while powering down Channels 3–4 during idle periods in TLV2765IN-based sensor hubs.

What is the typical input bias current of TLV2765IN over temperature?

The typical input bias current of TLV2765IN is 3 pA at 25°C and remains ≤200 pA across the full −40°C to +85°C industrial temperature range. This ultra-low Ib enables high-precision amplification of signals from megaohm-level sources such as pH electrodes, thermistors, and piezoelectric sensors without significant DC error in TLV2765IN circuits.

Can TLV2765IN drive capacitive loads without oscillation?

TLV2765IN is stable with capacitive loads ≤10 pF. For larger loads (e.g., ADC input capacitance or long traces), a series null resistor (RNULL ≥20 Ω) must be placed between the TLV2765IN output and the load to maintain phase margin >63° and prevent ringing. This requirement is documented in the "Driving a Capacitive Load" section of the TLV2765IN datasheet.
