Product details
Overview
TLV2474ID from Texas Instruments is a quad-channel, rail-to-rail input/output CMOS operational amplifier optimized for low-power, high-output-drive signal conditioning in single-supply systems. It delivers 2.8MHz gain-bandwidth, 600μA/channel supply current, ±35mA output drive at 500mV from rails, and 250μV typical input offset voltage across –40°C to +125°C. It is used in portable medical sensors, battery-powered data acquisition front-ends, and precision analog monitoring circuits.
For engineers reviewing the TLV2474ID datasheet, TLV2474ID pinout, TLV2474ID application, or TLV2474ID equivalent, key selection criteria include rail-to-rail I/O swing with 180mV rail margin under 10mA load, ultra-low shutdown current (1000nA/ch at 5V), 2.7V–6V supply flexibility, and TSSOP-14 packaging for space-constrained industrial designs.
Technical Context
The TLV2474ID employs a CMOS input stage enabling 2.5pA input bias current and rail-to-rail common-mode input range (0V to VDD). Its output stage supports true rail-to-rail swing-reaching within 180mV of each rail at ±10mA-and delivers ±35mA when operating 500mV from either supply rail.
It features internal compensation for unity-gain stability, operates over full industrial temperature (–40°C to +125°C), and includes no shutdown functionality (as confirmed by family package table: TLV2474 has "-" under SHUTDOWN column, unlike TLV2470/3/5). Shutdown capability is absent in TLV2474ID.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | 4 independent amplifiers - enables compact multi-signal conditioning without external routing. |
| Gain-bandwidth product | 2.8MHz - supports stable closed-loop operation up to ~200kHz with moderate gain (e.g., AV = 10). |
| Supply voltage range | 2.7V to 6V - compatible with Li-ion, 3.3V, and 5V systems without level-shifting. |
| Input offset voltage (typ) | 250μV - ensures ≤0.5% error in 500mV full-scale sensor interfaces at room temperature. |
| Output drive (±) | ±35mA at 500mV from rail - directly drives ADC reference buffers, LED drivers, or low-impedance transducers. |
| Input bias current | 2.5pA - minimizes voltage error across high-impedance sources (e.g., pH electrodes, photodiode TIA feedback). |
| Quiescent current / ch | 600μA - enables always-on operation in energy-sensitive applications with <2.4mA total quiescent draw. |
Pinout & Package
TSSOP-14 package: thermally enhanced, surface-mount, 4.4mm × 5mm footprint with 0.65mm pitch; suitable for automated assembly and moderate power dissipation (1022mW at TA ≤+25°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | Output (OUT1–OUT4) | Rail-to-rail outputs capable of sourcing/sinking ±35mA while staying within 500mV of supply rails. |
| 2, 6, 10, 14 | Inverting input (IN−1–IN−4) | High-impedance CMOS node; accepts signals from 0V to VDD with 2.5pA bias current. |
| 3, 7, 11, 12 | Non-inverting input (IN+1–IN+4) | Same rail-to-rail common-mode range as IN−; matched offset and bias for differential configurations. |
| 4 | VDD | Positive supply pin; must be decoupled locally (e.g., 100nF ceramic) to maintain PSRR >66dB. |
| 8 | GND | Analog ground reference; requires low-impedance connection to system ground plane for noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in 3.3V systems - e.g., 0–3.3V ADC interface without level shifters. |
| Low input bias current (2.5pA) | Preserves signal integrity from megaohm-level sources like piezoelectric sensors or high-R feedback networks. |
| High output drive (±35mA) | Eliminates need for external buffer stages when driving 10Ω–100Ω loads such as relay coils or DAC output buffers. |
| Wide supply range (2.7V–6V) | Supports direct integration into mixed-voltage boards - e.g., shares 3.3V rail with microcontrollers and ADCs. |
| Industrial temperature grade (–40°C to +125°C) | Validated for under-hood automotive, motor control feedback, and outdoor industrial sensor nodes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2474CDR | Same silicon, commercial temperature range (0°C to +70°C); identical electrical specs except wider offset max (2400μV vs 2000μV for I-suffix). | Not rated for extended industrial environments; unsuitable for under-hood or factory-floor deployments. | Select TLV2474CDR only for cost-sensitive consumer-grade products with ambient temperature control. |
| OPA2333PWR | Zero-drift architecture; 0.02μV/°C offset drift vs TLV2474ID's 0.4μV/°C; higher 350μA/ch current; no rail-to-rail output (clips ~200mV from rails). | Superior long-term DC stability but lower output drive (±25mA) and reduced voltage headroom limits use in low-VDD systems. | Choose OPA2333PWR where microvolt-level drift matters more than output swing or drive strength - e.g., precision weigh scales. |
Compared with TLV2474CDR, TLV2474ID offers guaranteed performance over –40°C to +125°C and tighter offset spec; versus OPA2333PWR, it trades zero-drift stability for higher output current, rail-to-rail swing, and lower quiescent power - making it optimal for wide-temperature, high-fidelity analog front-ends.

FAQ
Does TLV2474ID include a shutdown feature?
No, TLV2474ID does not include a shutdown function. Per the official TI family package table and pinout diagrams, only TLV2470, TLV2473, and TLV2475 variants have a dedicated SHDN pin; TLV2474ID uses all 14 pins for signal I/O and power, with no shutdown terminal. This is confirmed in the datasheet's "FAMILY PACKAGE TABLE" where TLV2474 shows "-" under the SHUTDOWN column.
What is the maximum capacitive load TLV2474ID can drive without instability?
TLV2474ID remains stable with capacitive loads ≤10pF when directly connected. For larger loads (e.g., ADC input capacitance or cable capacitance), TI recommends inserting a series null resistor (RNULL) of ≥20Ω between the output and load, as shown in Figure 42 of the datasheet. This isolates the amplifier's output stage from phase degradation caused by CL, preserving ≥61° phase margin even with 1000pF loads.
Can TLV2474ID operate from a single 2.7V supply while maintaining rail-to-rail output swing?
Yes, TLV2474ID is fully specified at 2.7V and maintains rail-to-rail output swing - delivering ±10mA while staying within 180mV of each rail, and ±35mA while staying within 500mV. At 2.7V, this yields usable output range of 0.18V to 2.52V under 10mA load, sufficient for interfacing with 12-bit SAR ADCs and low-voltage logic.
How does TLV2474ID's input offset voltage compare across temperature?
TLV2474ID has a typical input offset voltage of 250μV at +25°C, with a maximum of 2000μV over the full –40°C to +125°C range. Its offset temperature coefficient is 0.4μV/°C, meaning worst-case drift across the full range adds ≤66μV - contributing less than 0.003% error in a 2.2V full-scale system, making it suitable for stable DC-coupled measurements.
Is TLV2474ID pin-compatible with other quad op-amps in TSSOP-14 packages?
No, TLV2474ID is not pin-compatible with generic quad op-amps (e.g., LM324, MCP6004) due to its unique pin mapping: OUT1/IN−1/IN+1/VDD/OUT2/IN−2/IN+2/GND/OUT3/IN−3/IN+3/OUT4/IN−4/IN+4. This arrangement optimizes channel separation and layout symmetry but requires dedicated PCB design - no drop-in replacement exists without board revision.
