Product details
Overview
V62/21612-04XE from Texas Instruments is a radiation-hardened, extended-temperature bidirectional current-sense amplifier with zero-drift architecture, 132 dB CMRR, ±15 µV max offset voltage, and 50 µA typical quiescent current. It operates from 1.7 V to 5.5 V supply, supports –0.2 V to +40 V common-mode input range, and delivers precision microamp-level current measurement in avionics power monitoring circuits.
For engineers reviewing the V62/21612-04XE datasheet, V62/21612-04XE pinout, V62/21612-04XE application, or V62/21612-04XE equivalent, this page provides verified functional specifications, SOT-23-8 pin mapping, bidirectional sensing implementation details, and validated alternative options for high-reliability defense and aerospace current monitoring designs.
Technical Context
The V62/21612-04XE employs a capacitively coupled front-end amplifier followed by a difference amplifier output stage, enabling true rail-to-rail output swing (VS – 40 mV / GND + 1 mV) and ultra-low input bias current (±0.5 nA typ). Its zero-drift architecture ensures stable offset performance across –55°C to +150°C.
This device implements digital enable control (EN pin) to reduce supply current to <0.1 µA in shutdown, while maintaining high common-mode rejection (132 dB min) and gain accuracy (±0.2% for A1 variant) independent of supply voltage. The REF pin enables precise bidirectional current sensing via externally applied reference voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.7 V to 5.5 V - enables operation from single Li-ion or low-voltage industrial rails without level-shifting. |
| Common-Mode Range | –0.2 V to +40 V - supports direct high-side sensing on 28 V or 36 V bus systems, independent of VS. |
| Offset Voltage | ±15 µV max - extends dynamic range to sub-millivolt sense voltages, enabling use of <10 mΩ shunts. |
| Gain Error | ±0.2% (A1 variant) - limits total current measurement error at full scale to <0.2%, critical for closed-loop protection. |
| Quiescent Current | 50 µA typ enabled / 0.1 µA disabled - allows battery-powered periodic monitoring with minimal duty-cycle penalty. |
| CMRR | 132 dB min - rejects bus voltage transients in radar power supplies without introducing offset drift. |
| Input Bias Current | ±0.5 nA typ - permits use of RC filters on IN+/IN– without gain/offset degradation, improving EMI immunity. |
Pinout & Package
SOT-23-8 package (1.60 mm × 2.90 mm body), thermally enhanced for high-reliability mounting in constrained avionics enclosures.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VS (Pin 1) | Analog power supply | Accepts 1.7–5.5 V; powers internal amplifiers and enable logic; decoupling required per layout guidelines. |
| ENABLE (Pin 2) | Digital input control | Drives high to enable operation; drives low to place OUT in high-Z and reduce IQ to <0.1 µA. |
| REF (Pin 3) | Analog reference input | Sets output midpoint for bidirectional sensing; buffered reference required to maintain CMRR. |
| GND (Pin 4) | Analog ground reference | Return path for VS and signal chain; must be star-connected to minimize ground bounce in high-dI/dt systems. |
| OUT (Pin 5) | Analog voltage output | Delivers GAIN × (IN+ − IN−) + VREF; rail-to-rail swing supports 1.8 V MCU ADC interfacing. |
| NC (Pin 6) | No-connect terminal | Not internally bonded; must float or tie to GND/VS per layout best practices to avoid parasitic coupling. |
| IN+ (Pin 7) | Current-sense positive input | Connects to bus side of shunt in high-side config; load side in low-side config. |
| IN− (Pin 8) | Current-sense negative input | Connects to load side of shunt in high-side config; ground side in low-side config. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional current sensing | Enabled via external REF voltage; supports reversible motor drive or battery charge/discharge monitoring. |
| Zero-drift architecture | 80 nV/°C max offset drift - maintains calibration stability over full –55°C to +150°C military temperature range. |
| Ultra-low input bias current | ±0.5 nA typ - enables >1 kΩ RC filter on inputs without measurement error, critical for noisy radar power rails. |
| Rail-to-rail output | Swings to GND + 1 mV / VS – 40 mV - maximizes usable ADC range on 1.8 V microcontrollers in portable munitions. |
| Extended temperature qualification | –55°C to +150°C operating range with controlled baseline and traceable lot documentation per MIL-PRF-38535. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar current-sense amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| INA240-EP | Higher bandwidth (400 kHz vs. 87 kHz), higher gain error (±0.6%), no enable pin | Better suited for fast-switching motor control; lacks low-power shutdown mode for intermittent monitoring | Select when speed > accuracy and continuous operation is required |

FAQ
What is the maximum common-mode voltage supported by V62/21612-04XE?
V62/21612-04XE supports a common-mode input voltage range of –0.2 V to +40 V, independent of its 1.7 V to 5.5 V supply voltage. This allows direct high-side sensing on 28 V or 36 V aircraft bus systems without external level-shifting circuitry. The specification is guaranteed over the full –55°C to +150°C operating temperature range, making V62/21612-04XE suitable for engine-mounted avionics applications where bus transients exceed supply rails.
Does V62/21612-04XE support bidirectional current sensing, and how is it implemented?
Yes, V62/21612-04XE supports bidirectional current sensing via its dedicated REF pin. Applying a mid-supply reference voltage (e.g., VS/2) to REF centers the output voltage, allowing positive differential inputs (IN+ > IN−) to produce outputs above REF and negative differentials to produce outputs below REF. This eliminates the need for external op-amps or level-shifters. The V62/21612-04XE datasheet provides Equation 1 for calculating exact output voltage based on gain, RSENSE, ILOAD, and VREF.
What is the quiescent current of V62/21612-04XE in enabled and disabled states?
V62/21612-04XE draws 50 µA typical quiescent current when enabled and powered at 25°C, with a maximum of 90 µA across –55°C to +150°C. When the ENABLE pin is driven low, quiescent current drops to 10 nA typical (500 nA max over temperature), placing the output in high-impedance state. This ultra-low shutdown current makes V62/21612-04XE ideal for battery-powered munitions telemetry systems requiring long-term storage with periodic current sampling.
How does the zero-drift architecture of V62/21612-04XE improve measurement accuracy?
The zero-drift architecture of V62/21612-04XE achieves ±15 µV maximum offset voltage and 80 nV/°C maximum offset drift, significantly outperforming conventional amplifiers. This enables accurate microamp-level current measurements using high-value sense resistors and extends dynamic range for low-current fault detection. In V62/21612-04XE, the architecture uses auto-zeroing techniques that correct input-stage errors continuously, ensuring stable calibration across thermal cycles encountered in aerospace deployments.
Is V62/21612-04XE pin-compatible with other members of the INA190-EP family?
Yes, all INA190-EP variants-including V62/21612-04XE-are fully pin-compatible in the SOT-23-8 (DDF) package. They share identical pinout, electrical interface, and thermal characteristics. Gain selection (25 V/V, 50 V/V, etc.) is determined solely by part number suffix (A1–A5); no external configuration is needed. This allows design reuse across current ranges while maintaining layout compatibility and qualification continuity for V62/21612-04XE in existing EP-platform hardware.
