Overview
CT20308 is a buffered accurate reference voltage generator, including a low pass filter with an external capacitor for noise reduction and PSRR improvement. In order to achieve a total error <1%, the amplifier in the bandgap core block implements an offset cancellation circuitry.
Reference voltage thermal drift is minimized by means of 7 bits trimming so that the voltage reaches the “golden point”.
Additional 6 bits are used to flatten the output thermal characteristic while performing trimming at one single temperature.
CT20308 includes reference currents generators, both using an external accurate resistor and a completely internal one tied to poly resistor values.
CT20308 also includes an over temperature detection circuit and Power On Reset.
Key features
- VDD = 2.5 ÷ 5V
- Reference Voltage at VREF = 1.0V
- Reference voltage accuracy: ±0.4% in high performance (HP) mode, ±1% in low performance (LP) mode
- VREF integrated noise from 10Hz to 100kHz: <29µVrms in HP mode, <157µVrms in LP mode
