EVM User's guide:
Certificate:
The INA299 is a precise, bidirectional current sense amplifier that can measure voltage drops across shunt resistors over a wide common-mode range from –2V to 80V, independent of the supply voltage. The high-precision current measurement is achieved through a combination of low offset voltage (±150µV, maximum), small gain error (±0.25%, maximum) and a high DC CMRR (typical 120dB). The INA299 is not only designed for high voltage, bidirectional DC current measurements, but also for high-speed applications (such as transient detection and fast overcurrent protection) with a high signal bandwidth of 650kHz and fast settling time.
The INA299 operates from a single 2.7V to 12V supply, drawing 650µA of supply current. The INA299 is available in three gain options: 20V/V, 50V/V, 100V/V. Multiple gain options allow for optimization between available shunt resistor values and wide output dynamic range requirements.
The INA299 is specified over operating temperature range of −40°C to +125°C and is offered in a 6-pin SOT-23 package.
- Wide common-mode voltage:
- Operational voltage: −2V to +80V
- Survival voltage: −12V to +85V
- Bidirectional operation
- High small signal bandwidth: 650kHz (20V/V Gain)
- Slew rate: 2.5V/µs
- Step response settling time to 1%: 6.5µs
- High CMRR: 120dB
- Gain error (maximum) : ±0.25%, ±10ppm/°C drift
- Offset voltage (maximum): ±150µV, ±0.5µV/°C drift
- Operates from 2.7V to 12V supply
- Operational current: 650µA
- Available gains:
- INA299A1: 20V/V
- INA299A2: 50V/V
- INA299A3: 100V/V
