VSON (DRC)-10-9 mm² 3 x 3
The INA826S device is a low-cost instrumentation amplifier that offers extremely low power consumption along with shutdown and operates over a very wide single- or dual-supply range. A single external resistor sets any gain from 1 to 1000. The device offers excellent stability over temperature, even at G > 1, as a result of the low gain drift of only 35 ppm/°C (max).
The INA826S is optimized to provide excellent common-mode rejection ratio of over 100 dB (G = 10) over frequencies up to 5 kHz. At G = 1, the common-mode rejection ratio exceeds 84 dB across the full input common-mode range from the negative supply all the way up to 1 V of the positive supply. Using a rail-to-rail output, the INA826S is well-suited for low voltage operation from a 3-V single supply as well as dual supplies up to ±18 V.
Shutdown pins are provided to reduce supply current below 2 µA. Additional circuitry protects the inputs against overvoltage of up to ±40 V beyond the power supplies by limiting the input currents to less than 8 mA.
The INA826S is available in a 10-pin, 3-mm ×
3-mm VSON surface-mount package. The INA826S is specified over the –40°C to +125°C temperature range.
