STMicroelectronics TSU102
TSU102 - Nanopower (580nA) rail-to-rail I/O 5V CMOS Op-Amp
The TSU101, TSU102, and TSU104 operational amplifiers offer an ultra low-power consumption of 580 nA typical and 750 nA maximum per channel when supplied by 1.8 V. Combined with a supply voltage range of 1.5 V to 5.5 V, these features allow the TSU10x series to be efficiently supplied by a coin type Lithium battery or a regulated voltage in low-power applications.
The 8 kHz gain bandwidth of these devices make them ideal for sensor signal conditioning, battery supplied, and portable applications.
Features
- Submicro ampere current consumption: 580 nA typ at 25 °C at VCC = 1.8 V
- Low supply voltage: 1.5 V - 5.5 V
- Unity gain stable
- Rail-to-rail input and output
- Gain bandwidth product: 8 kHz typ.
- Low input bias current: 2 pA max at 25 °C
- Industrial temperature range: -40 °C to 85 °C
- Benefits:
- 42 years of typical equivalent lifetime supplied by a 220 mA.h coin-type Lithium battery
- Tolerance to power supply transient drops
- Accurate signal conditioning of high impedance sensors
STEVAL-IDI009V1 - Evaluation board for passive infrared sensor signal conditioning based on TSU102
The STEVAL-IDI009V1 evaluation board conditions the signal generated by a passive infrared (PIR) sensor, for common applications like human detection. A person in range of the sensor triggers a detection event, which can in turn be used to trip an alarm or command room lighting to be turned on, for example.
The board embeds the TSU102 operational amplifier which consumes only 1 µA. It is highly suitable for battery powered applications such as LED lighting with embedded motion detection to enhance daily comfort.
The global application consumes only 24 µA when there is no detection.
Features
- Allows motion detection with PIR sensor
- Suitable for home automation applications
- Based on TSU102 operational amplifier
- Band pass filter bandwidth from 0.7 Hz to 5 Hz
- Only 24 µA current consumption
- Detection area can be widened with Fresnel lens(not included)
- Compatible with NUCLEO boards
- Compatible with Arduino UNO R3
- RoHS compliant
