Product details
Overview
TLV2370IDR 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 supply current per channel, and operates from 2.7 V to 16 V - enabling use in Li-ion powered glucose meters and handheld test equipment.
For engineers reviewing the TLV2370IDR datasheet, TLV2370IDR pinout, TLV2370IDR application, or TLV2370IDR equivalent, key selection criteria include its rail-to-rail I/O capability, 25 µA shutdown current, −40°C to +125°C industrial temperature range, and SOT-23-6 package compatibility with space-constrained PCB layouts.
Technical Context
The TLV2370IDR employs CMOS input stage architecture enabling 1 pA input bias current and rail-to-rail common-mode input voltage range (0 V to VDD). Its internal compensation supports stable unity-gain operation with ≥65° phase margin into 100-pF capacitive loads.
Shutdown functionality is implemented via active-low SHDN pin, reducing supply current to 25 µA/channel while maintaining high impedance at IN+, IN−, and OUT. The device achieves 39 nV/√Hz input voltage noise and 0.02% THD+N at 10 kHz, making it suitable for precision DC-coupled and low-distortion AC signal paths.

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2371IDBVR | 5-pin SOT-23, no shutdown pin; identical electrical specs except SHDN omission | Lacks shutdown control - unsuitable for power-gated systems but simpler layout | Select when shutdown functionality is unnecessary and board space is constrained by pin count |
| OPA316IDBVR | Higher 10-MHz GBW, 6-V/µs slew rate, 400 µA supply current; no shutdown | Better AC performance but higher power; not drop-in due to different pinout and no SHDN | Choose for higher-speed signal chains where shutdown is managed externally or omitted |
Compared with TLV2371IDBVR, TLV2370IDR adds active shutdown control at minor cost in pin count; versus OPA316IDBVR, it trades bandwidth for lower power and integrated power management - making TLV2370IDR optimal for battery longevity over raw speed.

FAQ
What is the maximum supply voltage for TLV2370IDR?
The absolute maximum supply voltage for TLV2370IDR 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 rail-to-rail output swing and specified AC performance including 3-MHz bandwidth and 2.4 V/µs slew rate - critical for high-voltage sensor interfaces in industrial settings.
Does TLV2370IDR support true rail-to-rail input and output?
Yes, TLV2370IDR supports rail-to-rail input (common-mode range from 0 V to VDD) and rail-to-rail output (swing within 150 mV of each rail at 1-mA load). This is achieved via complementary CMOS input stage and push-pull output stage. At 2.7 V supply, VOH = 2.55 V and VOL = 0.1 V typical - enabling full utilization of ADC reference ranges in low-voltage systems.
How does the shutdown feature work on TLV2370IDR?
The SHDN pin on TLV2370IDR is active-low: pulling it to GND disables the amplifier core, reducing supply current to 25 µA/channel. Leaving SHDN floating or tied to VDD enables normal operation. Turnon/turnoff times are 0.8 µs and 1 µs respectively. During shutdown, IN+, IN−, and OUT present high impedance - preserving external circuit states without loading.
What is the input bias current specification for TLV2370IDR?
TLV2370IDR specifies an input bias current of 1 pA typical at 25°C, with maximum 60 pA over temperature. This ultra-low value stems from its CMOS input stage and enables high-accuracy interfacing with megohm-range sources like pH electrodes, photodiodes, and piezoelectric sensors - minimizing voltage errors caused by bias current flowing through source impedances.
Is TLV2370IDR compatible with lead-free reflow processes?
Yes, TLV2370IDR in SOT-23-6 (DBV) package is RoHS-compliant and qualified for standard lead-free reflow profiles per JEDEC J-STD-020. Peak temperature tolerance is 260°C for 10 seconds. The device's thermal metrics - including RθJA = 228.5°C/W for DBV - are validated for this process, ensuring reliable solder joint formation and long-term reliability in automated assembly lines.
