Product details
Overview
V62/21612-01XE from Texas Instruments is a radiation-hardened, bidirectional, zero-drift precision current-sense amplifier with enable functionality, designed for high-reliability aerospace and defense systems. It operates from 1.7 V to 5.5 V supply, supports –0.2 V to +40 V common-mode voltage, delivers ±15 µV max offset, 132 dB min CMRR, and 50 µA typical quiescent current at 25°C - enabling microamp-level current measurement in avionics power monitoring and radar system protection circuits.
For engineers reviewing the V62/21612-01XE datasheet, V62/21612-01XE pinout, V62/21612-01XE application, or V62/21612-01XE equivalent, this page provides verified functional specifications, SOT-23 (8) package mapping, temperature-stable gain error (±0.2% for A1 variant), bidirectional sensing capability via REF pin biasing, and validated alternatives for extended-life military-grade current sensing designs.
Technical Context
The V62/21612-01XE implements a capacitively coupled front-end architecture that blocks DC common-mode voltages while achieving ≥132 dB CMRR and <80 nV/°C offset drift - critical for stable operation across –55°C to +150°C. Its zero-drift design enables accurate low-current measurement without calibration over temperature and time.
It integrates an enable-controlled shutdown mode drawing ≤100 nA (typ), output high-impedance state when disabled, rail-to-rail output swing (GND +1 mV to VS –40 mV), and five factory-set gain options (25–500 V/V) - supporting both unidirectional and bidirectional sensing through externally applied REF voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.7 V to 5.5 V - enables direct interface with low-voltage microcontrollers and battery-backed systems without level-shifting. |
| Common-Mode Range | –0.2 V to +40 V - supports high-side sensing on 36-V bus rails and low-side sensing near ground, independent of supply voltage. |
| Offset Voltage | ±15 µV max - extends dynamic range to sub-millivolt sense voltages, permitting use of smaller shunt resistors with lower I²R loss. |
| Gain Error | ±0.2% (A1 variant) - ensures <2 mA absolute error in 1-A full-scale measurement, critical for overcurrent protection accuracy. |
| Quiescent Current | 50 µA typ (enabled), ≤100 nA (disabled) - reduces standby power in intermittently monitored subsystems such as missile guidance telemetry. |
| CMRR | 132 dB min - rejects bus voltage transients in radar pulse-power supplies, maintaining measurement integrity during EMI events. |
| Bandwidth | 45 kHz typ (A1, CL = 10 pF) - sufficient for closed-loop motor current feedback in electro-optical gimbal controllers. |
Pinout & Package
SOT-23 (8) package, 1.60 mm × 2.90 mm body size, thermally enhanced for high-reliability mounting in constrained avionics enclosures.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VS (Pin 1) | Analog power supply input | Accepts 1.7–5.5 V; powers internal amplifiers and reference circuitry; decoupling capacitor required at pin. |
| ENABLE (Pin 2) | Digital control input | Drives device ON (≥0.7×VS) or OFF (≤0.3×VS); disables output and reduces supply current to ≤100 nA. |
| REF (Pin 3) | Bidirectional offset reference | Sets zero-current output voltage; enables bidirectional sensing when biased to mid-supply (e.g., VS/2). |
| GND (Pin 4) | Analog ground reference | Primary return path for input stage and output buffer; must be connected to low-impedance system ground plane. |
| OUT (Pin 5) | Analog voltage output | Provides gain×(IN+−IN−)+VREF; rail-to-rail swing supports full utilization of ADC input range in 1.8-V systems. |
| NC (Pin 6) | No-connect terminal | Not internally bonded; must be left floating or tied to GND/VS per layout best practices - no electrical function. |
| IN+ (Pin 7) | Positive current-sense input | Connects to high-potential side of shunt in high-side config; or load side in low-side config - defines current direction polarity. |
| IN− (Pin 8) | Negative current-sense input | Connects to low-potential side of shunt in high-side config; or ground side in low-side config - completes differential measurement path. |
Key Features
| Feature | Design Value |
|---|---|
| Zero-drift architecture | ±15 µV max offset and ±80 nV/°C drift - eliminates thermal-induced baseline shift in thermal imaging power supplies. |
| Ultra-low input bias current | ±0.5 nA typ - permits use of >10 kΩ RC filters on IN+/IN− without gain/phase error, improving noise immunity in radar RF sections. |
| Extended temperature range | –55°C to +150°C operation - qualified for engine-mounted electronics and missile seeker housings without derating. |
| Controlled baseline manufacturing | Single fab/assembly/test site - ensures lot-to-lot parametric consistency critical for DO-254-compliant avionics hardware. |
| High common-mode rejection | 132 dB min CMRR - maintains <1 µV error under ±10 V common-mode step transients in ruggedized comms power converters. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision current-sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| INA240-EP | Higher bandwidth (350 kHz), higher quiescent current (2.4 mA), no enable pin, wider common-mode (–4 V to 80 V) | Better suited for fast-switching motor drives; less suitable for ultra-low-power munitions or battery-backed avionics | Select when speed > power efficiency; avoid if <100 nA shutdown current is required. |
| INA188-EP | Unidirectional only, no REF pin, lower CMRR (120 dB), same offset (±15 µV), same package | Applicable where reverse current detection is unnecessary, e.g., fixed-direction power converter output monitoring | Select for cost-sensitive unidirectional use cases; not viable for bidirectional sensing or REF-based zero-centering. |

FAQ
What is the maximum common-mode voltage supported by V62/21612-01XE?
V62/21612-01XE supports a common-mode input range of –0.2 V to +40 V, independent of its 1.7–5.5 V supply voltage. This allows direct high-side sensing on 36-V bus rails in avionics systems without external level-shifting circuitry, and ensures robust operation during voltage transients up to ±42 V as specified in absolute maximum ratings.
Does V62/21612-01XE support bidirectional current sensing?
Yes, V62/21612-01XE supports bidirectional current sensing via its REF pin. When a reference voltage (e.g., VS/2) is applied to REF, positive differential input yields OUT > VREF, and negative differential input yields OUT < VREF. This enables detection of current flow direction in radar modulator charge/discharge cycles and smart munitions safe/arm verification.
What is the gain option for V62/21612-01XE?
V62/21612-01XE is the A1 variant of the INA190-EP family, with a fixed gain of 25 V/V. This gain setting provides optimal trade-off between resolution and bandwidth (45 kHz typical) for applications such as 28-V aircraft bus monitoring where 100-mV full-scale sense voltage corresponds to 4-A load current using a 25-mΩ shunt.
How does the ENABLE pin function in V62/21612-01XE?
The ENABLE pin on V62/21612-01XE controls device power state: driven to VS (≥0.7×VS), it activates normal operation with 50 µA typical quiescent current; driven to GND (≤0.3×VS), it places OUT in high-impedance state and reduces supply current to ≤100 nA. This enables duty-cycled current monitoring in battery-powered munitions telemetry without compromising measurement fidelity.
What package type is used for V62/21612-01XE?
V62/21612-01XE uses the SOT-23 (8) package with nominal body dimensions of 1.60 mm × 2.90 mm. This thermally enhanced 8-pin variant supports fine-pitch automated assembly and meets MIL-PRF-38535 requirements for hermeticity and mechanical robustness in vibration-prone aerospace platforms.
