INA821IDR General Description

With super-beta input transistors, the INA821IDR delivers high precision with low input offset voltage, offset voltage drift, input bias current, and input voltage and current noise. This ensures accurate and reliable measurements, even in challenging environments. Additionally, the device incorporates protection circuitry to safeguard the inputs against overvoltage up to ±40 V, providing added peace of mind during operation

Key Features

Low offset voltage: 10 µV (typ), 35 µV (max)
Gain drift: 5 ppm/°C (G = 1),
35 ppm/°C (G > 1) (max)
Noise: 7 nV/√Hz
Bandwidth: 4.7 MHz (G = 1), 290 kHz (G = 100)
Stable with 1-nF capacitive loads
Inputs protected up to ±40 V
Common-mode rejection: 112 dB, G = 10 (min)
Power supply rejection: 110 dB, G = 1 (min)
Supply current: 650 µA (max)
Supply range:
- Single-supply: 4.5 V to 36 V
- Dual-supply: ±2.25 V to ±18 V
Specified temperature range: –40°C to +125°C
Packages: 8-pin SOIC, VSSOP, and WSON

Full compliance with description and image. Went, or rather crawled, two weeks.

Fast shipping and shipping. Everything works. Thank you!Lead acid, namely calcium batteries should not discharge less than to 11.8 v, otherwise they begin to lose their capacity. Usually inverters allow you to discharge the battery to 10 v which is very good (and good for manufacturers). To disconnect the load, you need to buy the relay at 220 v and connect this relay at the output of the inverter (load in the house). So the inverter will be able to charge the batteries after turning off the load and turning on the gasoline generator.
