Product details
Overview
TLV2374ID from Texas Instruments is a quad rail-to-rail input/output operational amplifier optimized for low-power, single-supply operation across 2.7 V to 16 V. It delivers 3 MHz bandwidth, 2.4 V/µs slew rate, and 550 µA per channel supply current, with shutdown capability (25 µA/channel in SHDN mode) and 1 pA input bias current - enabling precision sensing in battery-powered industrial and medical instrumentation.
For engineers reviewing the TLV2374ID datasheet, TLV2374ID pinout, TLV2374ID application, or TLV2374ID equivalent, key selection criteria include its rail-to-rail I/O swing at low voltage, shutdown control per channel pair, thermal performance in SOIC-14 (RθJA = 67 °C/W), and compatibility with Li-ion and MSP430-based systems requiring stable DC accuracy and dynamic response.
Technical Context
The TLV2374ID uses CMOS input stages to achieve 1 pA input bias current and rail-to-rail common-mode input range (0 V to VDD), supporting high-impedance sensor interfaces without external level-shifting. Its output stage drives rail-to-rail into 2 kΩ loads while maintaining phase margin ≥65° with 100 pF capacitive load.
Shutdown is implemented via two independent active-low control pins (pins 6 and 9): 1/2SHDN disables channels 1 & 2, 3/4SHDN disables channels 3 & 4. Turnon/turnoff times are 0.8 µs and 1 µs respectively, enabling fast power cycling in portable equipment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 16 V - supports single-cell Li-ion (3.0–4.2 V), dual alkaline (3 V), and ±8 V split supplies. |
| Bandwidth (GBW) | 3 MHz - enables stable unity-gain buffering of signals up to ~300 kHz with 0.1% settling in ≤2 µs. |
| Slew Rate | 2.4 V/µs - sustains full-scale 1-V step response within 0.42 µs, critical for pulse amplification in glucose meters. |
| Input Bias Current | 1 pA - minimizes voltage error in high-Z pH or thermopile sensor front-ends (e.g., <1 µV error at 1 MΩ source). |
| Shutdown Current | 25 µA/channel - reduces total quiescent draw to 100 µA for all four op-amps, extending battery life in handheld test gear. |
| Input Offset Voltage | 4.5 mV (typ) - ensures <±5 mV DC error in 12-bit ADC driver applications without trimming. |
| Operating Temperature | −40°C to +125°C - qualified for industrial automation and automotive cabin-sensing environments. |
Pinout & Package
TLV2374ID is supplied in a 14-pin SOIC package (body size 8.65 mm × 3.91 mm) with standard JEDEC MS-012AC footprint and exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Amplifier 1 output - rail-to-rail capable, drives 2 kΩ load to within 150 mV of rails at 1 mA. |
| 2 | 1IN− | Inverting input, channel 1 - high-impedance CMOS node; requires matched trace capacitance for stability. |
| 3 | 1IN+ | Noninverting input, channel 1 - accepts common-mode voltages from GND to VDD. |
| 4 | VDD | Positive supply - decoupling capacitor (0.1 µF ceramic) required within 5 mm of this pin. |
| 5 | 2IN+ | Noninverting input, channel 2 - electrically isolated from channel 1 inputs; no crosstalk > −80 dB @ 10 kHz. |
| 6 | 2IN− | Inverting input, channel 2 - shares same input stage architecture and offset drift as pin 2. |
| 7 | 2OUT | Amplifier 2 output - identical AC/DC specs to pin 1; may be paralleled for higher output current. |
| 8 | GND | Analog ground reference - must connect to low-impedance PCB plane; separate from digital ground if mixed-signal. |
| 9 | 3/4SHDN | Shutdown enable for channels 3 & 4 - logic-low (<0.8 V) disables both; floating defaults to active (enabled). |
| 10 | 3IN+ | Noninverting input, channel 3 - pin-compatible with TLC2274 but adds shutdown and lower VDD(min). |
| 11 | GND | Second ground pin - ties internal substrate; must be connected to same analog ground net as pin 8. |
| 12 | 3IN− | Inverting input, channel 3 - matches pin 2/6 electrical characteristics; supports differential input configurations. |
| 13 | 4IN− | Inverting input, channel 4 - layout symmetry with pins 2/6/12 recommended to minimize mismatch. |
| 14 | 4OUT | Amplifier 4 output - fully specified for rail-to-rail swing and 16 mA short-circuit current limit. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC2274CD | No shutdown function; higher 1100 µA/channel supply current; 300 µV max VOS vs TLV2374ID's 4.5 mV typ. | Lacks power-gating capability; unsuitable for duty-cycled portable instruments requiring ultra-low standby current. | Select when lowest input offset is critical and continuous operation is guaranteed. |
| TLV2464CD | Higher 550 µA/channel supply current but 6.4 MHz GBW and 1.6 V/µs slew rate; no shutdown; rail-to-rail output only (not input). | Better AC performance but incompatible with rail-to-rail input requirements in single-supply sensor interfaces. | Select when bandwidth >3 MHz is needed and input common-mode range can be limited to VDD/2 ±1.5 V. |
Compared with TLC2274CD and TLV2464CD, TLV2374ID uniquely combines rail-to-rail input/output, shutdown control, and sub-600 µA/channel consumption - making it the only option among the three for battery-powered systems needing both precision DC performance and dynamic power management.

FAQ
What is the maximum supply voltage for TLV2374ID?
The absolute maximum supply voltage for TLV2374ID is 16.5 V, but the recommended operating range is 2.7 V to 16 V. Operation above 16 V risks permanent damage. At 16 V, the device maintains full rail-to-rail output swing and 3 MHz bandwidth, enabling compatibility with ±8-V split supplies or high-voltage battery stacks.
Does TLV2374ID support true rail-to-rail input?
Yes, TLV2374ID supports rail-to-rail input - its common-mode input voltage range extends from GND to VDD across the full −40°C to +125°C temperature range. This allows direct interfacing with sensors whose output spans the entire supply rail, eliminating the need for external level-shifting networks in single-supply designs.
How does the shutdown feature work on TLV2374ID?
TLV2374ID has two independent active-low shutdown pins: pin 6 (1/2SHDN) disables channels 1 and 2, and pin 9 (3/4SHDN) disables channels 3 and 4. Driving either pin below 0.8 V places its associated pair into shutdown, reducing supply current to 25 µA per channel. Floating these pins leaves the corresponding channels enabled.
Can TLV2374ID drive capacitive loads?
TLV2374ID is stable with capacitive loads up to 100 pF, as confirmed by phase margin ≥65° in the datasheet. For loads >100 pF, an isolation resistor (10–100 Ω) between the output and capacitance is recommended. The device's unity-gain bandwidth shifts predictably with load, and settling time remains within 2 µs for 0.1% accuracy with 47 pF and 2 kΩ.
What is the input offset voltage specification for TLV2374ID?
TLV2374ID has a typical input offset voltage of 4.5 mV at 25°C, with a maximum of 6 mV over the full −40°C to +125°C industrial temperature range. This value is measured with VIC = VDD/2 and RS = 50 Ω. The offset drift is 2 µV/°C, contributing <±0.25 mV error across a 125°C span.
