Product Description
Product Features The INA333 is a low-power, precision instrumentation amplifier with excellent accuracy. The gain can be set from 1 to 1000 using a single external resistor. The INA333 is designed to use the industry-standard gain formula: G = 1 + (100 kΩ / RG). |
Product Parameters Low offset voltage: 25μV (max), G ≥ 100 Low drift: 0.1μV/°C, G ≥ 100 Low noise: 50nV/√Hz, G ≥ 100 High common-mode rejection ratio (CMRR): 100dB (minimum), G ≥ 10 Low input bias current: 200pA (max) Low quiescent current: 50μA Input voltage: (V–) + 0.1V to (V+) – 0.1V Output voltage: (V–) + 0.05V to (V+) – 0.05V Operating temperature range: -40°C to +125°C Filtered radio frequency interference (RFI) input Power supply range: 1.8V to 5.5V (single supply), ±0.9V to ±2.75V (dual supply) |
Applications Bridge amplifiers, electrocardiogram (ECG) amplifiers, pressure sensors, medical instruments, portable instruments, thermocouple amplifiers, resistance temperature detector (RTD) sensor amplifiers, data acquisition, etc. |
Instructions The onboard 3.3V low-dropout (LDO) regulator directly powers the INA333 amplifier. The amplifier uses a single-ended power supply, with V- connected to GND and V+ connected to the LDO's 3.3V output. This amplifier uses a 3.3V single-ended power supply. VIN+ and VIN- are the non-inverting inputs. R3 on the board is not soldered. The VCC regulator LDO input is 5V. Package Included: 1 x INA333 Multi-Purpose Triple Op Amp, Precision Instrumentation Amplifier |
