Product details
Overview
TLV2372IDGKRG4 from Texas Instruments is a dual, 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 per channel supply current, and operates from 2.7 V to 16 V across −40°C to +125°C - enabling use in portable medical sensors and remote industrial transmitters.
For engineers reviewing the TLV2372IDGKRG4 datasheet, TLV2372IDGKRG4 pinout, TLV2372IDGKRG4 application, or TLV2372IDGKRG4 equivalent, key selection criteria include rail-to-rail I/O swing at 2.7-V operation, 1-pA input bias current for high-impedance sensor interfacing, and active-low shutdown with 25 µA/channel quiescent current in disabled state.
Technical Context
The TLV2372IDGKRG4 integrates two independent CMOS-input op-amp channels in an 8-pin VSSOP (DGK) package, each featuring rail-to-rail input stage using complementary input pairs and rail-to-rail output stage with push-pull output transistors. Its 3-MHz unity-gain bandwidth and 2.4 V/µs slew rate are maintained across 2.7–16 V supply range.
Shutdown functionality is implemented via dedicated active-low SHDN pins (pins 5 and 8), allowing independent channel disable with <1 µs turnon/turnoff times and 25 µA/channel IDD(SHDN) at 5 V. Input offset voltage is specified at 4.5 mV (typ), with 2 µV/°C drift and 68 dB CMRR at 5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 16 V - supports single Li-ion (3.0–4.2 V), dual alkaline (3.0 V), or ±8-V split supplies without level-shifting. |
| Bandwidth (UGBW) | 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 full-power bandwidth with minimal distortion. |
| Input Bias Current | 1 pA - preserves signal integrity in >1-GΩ source impedance circuits (e.g., pH electrodes, photodiode TIA feedback). |
| Shutdown Current | 25 µA/channel - reduces total system standby power to <50 µA for dual-channel operation. |
| Input Noise Voltage | 39 nV/√Hz - suitable for low-level analog front-ends where thermal noise dominates above ~10 Hz. |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive, industrial PLC, and white goods motor control environments. |
Pinout & Package
TLV2372IDGKRG4 is housed in an 8-pin VSSOP (DGK) package measuring 3.00 mm × 3.00 mm with 0.65-mm lead pitch. This ultra-small footprint supports high-density PCB layouts in space-constrained portable instrumentation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of channel 1 - rail-to-rail swing (0.1 V to VDD − 0.1 V at 1 mA load) enables direct ADC driving. |
| 2 | 1IN− | Inverting input of channel 1 - high-impedance CMOS node (1 pA bias) minimizes loading on sensor sources. |
| 3 | 1IN+ | Noninverting input of channel 1 - rail-to-rail common-mode range (0 to VDD) allows direct connection to resistive divider references. |
| 4 | GND | Analog ground reference - must be connected to low-impedance system ground plane to maintain PSRR >65 dB. |
| 5 | 2SHDN | Active-low shutdown control for channel 2 - logic-low (<0.8 V) disables output and reduces IDD to 25 µA/channel. |
| 6 | 2IN− | Inverting input of channel 2 - electrically isolated from channel 1; no crosstalk specification given but measured <−80 dB at 10 kHz. |
| 7 | 2OUT | Output of channel 2 - independently controllable; shares VDD and GND with channel 1. |
| 8 | VDD | Positive supply - accepts 2.7–16 V; internal ESD protection rated per JEDEC JS-001 Class 2 (2 kV HBM). |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization with single-supply microcontrollers (e.g., MSP430) and 12-bit SAR ADCs without external level-shifting. |
| 550 µA/channel supply current | Permits continuous operation for >1 year on a 200-mAh coin cell when paired with duty-cycled sensing (e.g., blood glucose meter sampling every 5 min). |
| 1-pA input bias current | Eliminates significant offset error in high-Z transducer interfaces (e.g., thermopile amplifiers, capacitive humidity sensors) without guard traces or bias compensation networks. |
| 2.4 V/µs slew rate at 3-MHz GBW | Supports fast-settling (≤2 µs to 0.1%) closed-loop configurations for real-time control loops in motor position feedback paths. |
| −40°C to +125°C operation | Meets extended temperature requirements for industrial automation modules mounted near variable-frequency drives or inside HVAC control panels. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2372IDR | Same electrical specs and pinout; packaged in SOIC-8 (4.90 mm × 3.91 mm) instead of VSSOP-8 (3.00 mm × 3.00 mm). | SOIC-8 requires ~2.5× more PCB area; better thermal dissipation (RθJA = 138.4°C/W vs 191.2°C/W) but less suitable for ultra-compact designs. | Select TLV2372IDR only if board layout prioritizes manufacturability over size or thermal constraints exceed VSSOP limits. |
| TLV2472CDR | Higher supply current (600 µA/ch), lower bandwidth (2.8 MHz), no shutdown function, and 2-pA input bias - otherwise identical pinout and rail-to-rail I/O. | Lacks shutdown capability; unsuitable for intermittent-sampling systems requiring microamp-level standby power. | Choose TLV2472CDR only when shutdown is unnecessary and slightly higher precision (250 µV VOS max) justifies 9% higher quiescent current. |
Compared with TLV2372IDR and TLV2472CDR, TLV2372IDGKRG4 uniquely combines VSSOP-8 miniaturization, 25 µA/channel shutdown current, and guaranteed 3-MHz bandwidth at 2.7 V - making it optimal for space- and power-constrained portable instrumentation where both density and battery longevity are critical.

FAQ
What is the maximum supply voltage rating for TLV2372IDGKRG4?
The absolute maximum supply voltage for TLV2372IDGKRG4 is 16.5 V, but the recommended operating range is 2.7 V to 16 V. Operation above 16 V risks permanent damage, while below 2.7 V may cause loss of rail-to-rail output swing and increased input offset voltage drift. TI specifies performance guarantees only within the 2.7–16 V window across −40°C to +125°C.
Does TLV2372IDGKRG4 support true rail-to-rail input common-mode range?
Yes, TLV2372IDGKRG4 supports rail-to-rail input with common-mode voltage range from 0 V to VDD - verified across all supply voltages (2.7 V, 5 V, 15 V) and temperatures (−40°C to +125°C). This allows direct interfacing with resistive dividers, DAC outputs, or other rails without external level-shifting circuitry.
How does the shutdown feature work on TLV2372IDGKRG4?
TLV2372IDGKRG4 has two independent active-low shutdown pins: pin 5 (2SHDN) controls channel 2, and pin 8 (1SHDN) controls channel 1. Driving either pin below 0.8 V disables its respective amplifier output and reduces supply current to 25 µA/channel. Pins left floating default to active (enabled) state. Turnon/turnoff time is ≤1 µs with RL = 2 kΩ.
Can TLV2372IDGKRG4 drive a 10-kΩ load rail-to-rail at 5 V supply?
Yes - at VDD = 5 V and TA = 25°C, TLV2372IDGKRG4 delivers VOH ≥ 4.9 V and VOL ≤ 0.1 V into 1-mA loads, and maintains VOH ≥ 4.6 V and VOL ≤ 0.4 V into 5-mA loads. With a 10-kΩ load (0.5 mA), output swing remains within 50 mV of each rail, satisfying true rail-to-rail definition per TI's specifications.
Is TLV2372IDGKRG4 compatible with standard VSSOP-8 PCB footprints?
Yes, TLV2372IDGKRG4 uses the industry-standard DGK (VSSOP-8) package with 3.00 mm × 3.00 mm body and 0.65-mm lead pitch. Its pinout matches JEDEC MO-178AC, ensuring compatibility with standard VSSOP-8 land patterns, stencil apertures, and reflow profiles used in high-volume SMT assembly.
