| |
| Features |
| Operating current < 0.5mA |
| Sleep Current < 200nA |
| Supply Voltage 1.6V-3.6V |
| Operating temperature: -40C to +125C |
| Available in bare-die or RoHS 28-pin MLF/QFN packages. |
| Fully integrated solution requires only 3 discretes plus any sensor components. |
| SPI digital serial data communication |
| Drives and measures sensors |
| Measurement technique is similar to a relaxation oscillator and uses LR or RC networks. Adjustable DACs allow independent adjustment of high and low voltage swings � allowing bias adjustment on each sensor. |
| Internal or external clock; higher frequencies lead to improved
resolution and shorter sampling time. |
| All chip functions and settings are controllable from the serial
interface using a register-based architecture. |
| Count-up and subtract-down option for back-to-front sensor measurements. |
