Design & Manufacture
Mouser now stocks the Texas Instruments (TI) PGA308, a single-supply
auto-zero programmable analog sensor signal conditioner. The analog signal
path amplifies the sensor signal and provides digital calibration for offset
and gain. Calibration is done via the 1W pin. This is a digital One-Wire,
UART-compatible interface. For three-terminal sensor modules, 1W may be
connected to VOUT. Then the assembly can be programmed through the VOUT pin.
Gain and offset calibration parameters are stored on-board in seven banks of
one-time programmable (OTP) memory. The power-on reset (POR) OTP bank may be
programmed a total of four times.
Applications include bridge sensors, remote 4-20mA transmitters, strain,
load, weigh scales and automotive sensors.
