Product details
Overview
TLV2370IP 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 operates from 2.7 V to 16 V, delivers 3 MHz bandwidth and 2.4 V/µs slew rate at 550 µA per channel, and supports −40°C to +125°C operation - enabling use in portable blood glucose meters and remote sensing front-ends.
For engineers reviewing the TLV2370IP datasheet, TLV2370IP pinout, TLV2370IP application, or TLV2370IP equivalent, key selection criteria include its rail-to-rail I/O capability, 25 µA shutdown current, 1 pA input bias current, 39 nV/√Hz input noise, and compatibility with Li-ion and MSP430-based microcontroller supply rails.
Technical Context
The TLV2370IP uses CMOS input stage architecture to achieve ultra-low input bias current (1 pA) and rail-to-rail common-mode input range (0 V to VDD), supporting high-impedance sensor interfaces without external level-shifting. Its fully differential output stage enables true rail-to-rail swing under load, maintaining >2.55 V high-level and <0.15 V low-level output voltage at 1 mA with 2.7 V supply.
Shutdown functionality is implemented via active-low SHDN pin (pin 5 in SOIC-8), reducing supply current to 25 µA/channel while preserving fast turnon/turnoff times (0.8 µs / 1 µs). The device is internally compensated for unity-gain stability with 65° phase margin into 100 pF capacitive load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 16 V - supports single-cell Li-ion (3.0–3.7 V), dual alkaline (3 V), and ±1.35 V to ±8 V split supplies. |
| Bandwidth (GBW) | 3 MHz - enables stable closed-loop gain ≥10 at 300 kHz for anti-aliasing and active filter applications. |
| Slew Rate | 2.4 V/µs - supports 1-Vpp signals up to ~380 kHz without slew-induced distortion. |
| Input Bias Current | 1 pA - permits direct connection to >1 GΩ sensors (e.g., pH electrodes, piezoresistive strain gauges) without significant offset error. |
| Shutdown Current | 25 µA/channel - reduces system standby power by >95% vs active mode (550 µA), critical for duty-cycled instrumentation. |
| Input Noise Voltage | 39 nV/√Hz - limits RMS noise to ~1.2 µV in 10 kHz bandwidth, suitable for 12-bit ADC front-ends. |
| Operating Temperature | −40°C to +125°C - qualified for industrial automation, white goods motor control, and automotive cabin electronics. |
Pinout & Package
TLV2370IP is packaged in an 8-pin SOIC (D package) with 4.90 mm × 3.91 mm body size and standard JEDEC MS-012AC footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Amplifier output - drives loads up to ±7 mA at 5 V supply; rail-to-rail swing enables full dynamic range utilization of downstream ADCs. |
| 2 | IN− | Inverting input - high-impedance node (1 pA bias) for feedback networks and differential configurations. |
| 3 | IN+ | Noninverting input - accepts common-mode voltages from 0 V to VDD, eliminating need for input biasing resistors in single-supply designs. |
| 4 | GND | Analog ground reference - must be connected to low-impedance system ground plane to maintain PSRR (>70 dB) and noise immunity. |
| 5 | NC | No internal connection - electrically isolated; may be left unconnected or tied to GND for mechanical stability. |
| 6 | NC | No internal connection - electrically isolated; no routing or termination required. |
| 7 | VDD | Positive supply - decoupling capacitor (0.1 µF ceramic) required within 5 mm for stable high-frequency operation. |
| 8 | SHDN | Active-low shutdown control - logic-low (<0.8 V) disables amplifier; floating or logic-high (>2 V) enables operation. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full-scale signal acquisition from 0 V to VDD without external level-shifting or dual supplies. |
| 550 µA/channel supply current | Supports continuous operation in handheld test equipment with >100-hour battery life on two AA cells. |
| 25 µA/channel shutdown current | Reduces quiescent power to <1 µW per channel, enabling microcontroller-controlled sleep modes in portable medical devices. |
| 39 nV/√Hz input voltage noise | Preserves SNR in low-amplitude sensor amplification (e.g., thermopile, ECG electrode) without requiring post-amplification filtering. |
| 1 pA input bias current | Eliminates leakage-induced offset in high-Z transducer interfaces, avoiding calibration drift over temperature and time. |

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 variant without shutdown pin; identical electrical specs except IDD(SHDN) not applicable. | Used where board space is constrained and shutdown is unnecessary (e.g., always-on sensor nodes). | Select TLV2371IDBVR only if PCB layout cannot accommodate SOIC-8 footprint and shutdown is not required. |
| TLC2271CD | Higher supply current (1100 µA/channel); no shutdown; 2.2 MHz GBW; 3.6 V/µs slew rate; O-only rail-to-rail output. | Preferred in higher-speed, non-battery applications where power efficiency is secondary to drive strength. | Choose TLC2271CD when driving heavy capacitive loads (>1000 pF) or requiring faster settling than TLV2370IP provides. |
Compared with TLV2371IDBVR and TLC2271CD, the TLV2370IP uniquely combines shutdown capability, rail-to-rail input/output, and sub-600 µA quiescent current in an industry-standard SOIC-8 package - making it optimal for space-constrained, battery-sensitive industrial and medical instrumentation where dynamic power management is essential.

FAQ
What is the maximum supply voltage for TLV2370IP?
The absolute maximum supply voltage for TLV2370IP 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 3 MHz bandwidth and rail-to-rail output swing, enabling compatibility with ±8-V split supplies or high-voltage single-ended systems such as industrial PLC analog I/O modules.
Does TLV2370IP support rail-to-rail input at all supply voltages?
Yes, TLV2370IP supports rail-to-rail input common-mode range (0 V to VDD) across its entire 2.7 V to 16 V supply range. This is confirmed in the datasheet's Recommended Operating Conditions table and Electrical Characteristics section, where VCM = 0 to VDD is specified for all tested VDD values including 2.7 V, 5 V, and 15 V - enabling direct interfacing with sensors whose output spans the full supply rail.
How does the shutdown function operate on TLV2370IP?
The TLV2370IP shutdown pin (pin 8) is active-low: pulling it below 0.8 V disables the amplifier and reduces supply current to 25 µA/channel, while leaving it open or tying it to VDD (>2 V) enables normal operation. Turnon/turnoff times are 0.8 µs and 1 µs respectively, allowing rapid power cycling in microcontroller-driven systems without signal interruption delays.
Can TLV2370IP drive a 10-kΩ load with rail-to-rail output swing?
Yes, TLV2370IP delivers rail-to-rail output swing into 10-kΩ loads across its full temperature and supply range. At 2.7 V supply and 25°C, VOH = 2.58 V and VOL = 0.15 V at 1 mA - representing 95% and 5% of VDD respectively. Even at 125°C, VOH remains ≥2.48 V and VOL ≤0.22 V, ensuring >90% usable dynamic range for 12-bit ADC interfacing.
Is TLV2370IP suitable for high-impedance pH electrode interfaces?
Yes, TLV2370IP is well-suited for pH electrode interfaces due to its 1 pA typical input bias current and rail-to-rail input stage. With electrode impedances often exceeding 100 MΩ, this low bias current minimizes voltage error (e.g., <10 µV error at 10 MΩ source impedance), preserving measurement accuracy without requiring guard rings or T-network compensation - a key advantage over higher-bias alternatives like TLC227x.
