What are the key features of LEOAD128PT?
- 10-bit successive approximation ADC with 2 analog input channels completes conversion in as little as 20 µs for real-time signal monitoring
- 0.0488% maximum linearity error ensures high-accuracy digitization suitable for precision measurement and calibration instruments
- -0.05 V to 5.05 V analog input range directly interfaces with standard 0-5 V sensor outputs without external level shifting
What is LEOAD128PT used for?
The LEOAD128PT suits precision analog data acquisition in industrial process control instruments, where 10-bit resolution and 20 µs conversion time meet the demands of slow-to-medium-speed sensor polling for temperature, pressure, or flow transducers. Its 2-channel input and 8-pin DIP package make it straightforward to prototype on breadboards and integrate into legacy designs requiring a simple serial ADC interface. Low-volume scientific measurement equipment and educational development boards also benefit from its accurate successive approximation architecture.

Frequently Asked Questions
What is the maximum conversion time of LEOAD128PT and how does it affect sampling throughput?
The LEOAD128PT completes one 10-bit conversion in a maximum of 20 µs, corresponding to a maximum sample rate of approximately 50 kSPS. This throughput suits slow-to-medium-speed measurements such as temperature, humidity, and pressure monitoring in industrial instruments and data loggers.
How many analog input channels does LEOAD128PT support and what voltage range do they accept?
The device provides 2 analog input channels accepting signals from -0.05 V to 5.05 V. This range directly interfaces with standard 0-5 V industrial sensors and signal conditioning circuits without requiring external level translators, simplifying the analog front-end design.
What linearity error specification does LEOAD128PT guarantee and why does it matter for calibration applications?
The LEOAD128PT guarantees a maximum linearity error of 0.0488%, corresponding to approximately 0.5 LSB at 10-bit resolution. This accuracy level allows the device to be used in calibration instruments and precision voltage measurement tools where mid-scale non-linearity would otherwise introduce systematic measurement errors.
Why might an engineer choose the 8-pin DIP package of LEOAD128PT over a surface-mount ADC?
The 8-pin DIP (R-PDIP-T8) package fits IC sockets and solderless breadboards, enabling quick prototyping and in-field replacement without SMT equipment. It is preferred in low-volume industrial instruments, educational labs, and legacy system retrofits where through-hole assembly or socketed components are standard practice.
