Texas Instruments TLV2370ID

Overview

TLV2370ID from Texas Instruments is a single-channel, rail-to-rail input and output operational amplifier with shutdown control, designed for low-power precision signal conditioning in battery-powered and industrial systems. It delivers 3-MHz bandwidth, 2.4 V/µs slew rate, 550 µA/channel supply current, and operates from 2.7 V to 16 V across −40°C to +125°C. It is used in portable medical sensors and handheld test equipment where rail-to-rail swing and low quiescent current are critical.

For engineers reviewing the TLV2370ID datasheet, TLV2370ID pinout, TLV2370ID application, or TLV2370ID equivalent, key selection criteria include its shutdown-enabled power management (25 µA/channel in SHDN), ultra-low input bias current (1 pA), rail-to-rail I/O capability at 2.7-V operation, and compatibility with Li-ion and MSP430-based systems.

Technical Context

The TLV2370ID uses CMOS input stage architecture enabling high-impedance sensor interfacing and 1-pA input bias current. Its rail-to-rail input stage supports common-mode voltage from ground to VDD, while rail-to-rail output delivers >98% of full supply swing under 1-mA load.

Shutdown functionality is implemented via active-low SHDN pin, with turnon/turnoff times of 0.8 µs and 1.0 µs respectively, and IDD(SHDN) = 25 µA/channel at 2.7–5 V. The device maintains stable unity-gain operation with ≥65° phase margin into 100-pF capacitive loads.

Manufacturer

Texas Instruments is a global semiconductor company headquartered in Dallas, Texas, delivering analog and embedded processing solutions for industrial, automotive, and personal electronics markets.

The TLV237x family was developed to extend rail-to-rail op-amp performance to 16-V supplies while maintaining sub-1-pA input bias and 550-µA quiescent current-targeting battery-powered and high-impedance sensor signal chains.

FAQ

What is the maximum supply voltage for TLV2370ID?

The absolute maximum supply voltage for TLV2370ID is 16.5 V, with recommended operating range from 2.7 V to 16 V. Operation above 16 V risks permanent damage. At 16 V, the device delivers rail-to-rail output swing and maintains 3-MHz bandwidth, making it compatible with ±8-V split supplies or high-voltage single-cell LiPo systems. Always observe thermal limits: RθJA = 138.4°C/W in SOIC package.

Does TLV2370ID support true rail-to-rail input at 2.7 V supply?

Yes, TLV2370ID supports rail-to-rail input common-mode range from 0 V to VDD across its full operating temperature range (−40°C to +125°C) at 2.7 V supply. This is enabled by its CMOS input stage, allowing direct interfacing with sensors whose output spans ground to supply without external level-shifting. Input offset voltage remains ≤6 mV over temperature, ensuring accuracy in low-voltage signal chains.

How does the shutdown feature of TLV2370ID behave during power-up?

TLV2370ID's SHDN pin is active-low and internally pulled up; when left floating, the amplifier remains enabled. During power-up, if SHDN is driven low before VDD stabilizes, the device enters shutdown and draws only 25 µA/channel. Once VDD exceeds 2.7 V and SHDN rises above 2 V, turnon occurs within 0.8 µs. No power-up sequencing constraints apply-VDD and SHDN may ramp simultaneously.

Can TLV2370ID drive a 10-kΩ load rail-to-rail at 15 V supply?

Yes, TLV2370ID drives 10-kΩ loads rail-to-rail at 15 V supply: VOH = 14.9 V and VOL = 0.08 V at 1 mA (typical), meeting rail-to-rail definition (<150 mV from rails). At 5 mA, VOL rises to 0.3 V and VOH drops to 14.7 V-still within 300-mV compliance. For 10-kΩ, output swing exceeds 99% of VDD, preserving dynamic range in high-precision DAC buffers and sensor interfaces.

Is TLV2370ID pin-compatible with other TLV237x variants in SOIC-8?

No, TLV2370ID is not pin-compatible with TLV2372ID or TLV2373ID in SOIC-8. TLV2370ID uses a single-amplifier + shutdown configuration (Pin 8 = SHDN), whereas TLV2372ID (dual) assigns Pin 8 to VDD and has no shutdown. TLV2373ID (dual with shutdown) uses 14-pin SOIC. Only TLV2371ID shares the same 8-pin SOIC footprint but lacks SHDN (Pin 8 = NC), making TLV2370ID a unique 8-pin variant with integrated power control.
