SSP54123

SSP54123 is designed for use in earth leakage circuit interrupters for operation directly off the AC line in breakers; It includes voltage regulator,amplifier, Latch, etc. The circuits can absorb the external surge voltage and improve the anti-interference ability of the chip in high voltage, spike pulse and high-frequency electromagnetic. Improve the chip Stable reliability.

SSP1922

SSP1922 is a high accurate time measurement (TDC) circuit. SSP1922 integrates analog comparator, analog switch, Schmidt flip-flop and other internal devices, thus greatly simplifying the peripheral circuit. At the same time, the first wave detection function is added inside, so that the anti-interference ability is greatly improved. The programmable offset range of the comparator is increased to ±35mV, the sampling accuracy can be improved.Measuring the relative pulse width of the first wave gives the user an indication of the strength of the received signal. Through this hint, we can judge the abnormal detection of ultrasonic transducer, the increase of wall covering, the presence of bubbles in water and so on. The Start-TOF-Restart command can complete a measurement of ultrasonic time difference (upstream and downstream) and data reading, so as to greatly reduce the software operation and power consumption. Compatible with TDC - GP22.

SSP1120

The SSP1120 is a precision, 16-bit, analog-to-digital converter (ADC) that offers many integrated features to reduce system cost and component count in applications measuring small sensor signals. The device can perform conversions at data rates up to 2000 samples-per-second (SPS) with single-cycle settling. At 20 SPS, the digital filter offers simultaneous 50-Hz and 60-Hz rejection for noisy industrial applications. The internal PGA offers gains up to 128 V/V. This PGA makes the SSP1120 ideally suited for applications measuring small sensor signals, such as resistance temperature detectors (RTDs), thermocouples, thermistors, and bridge sensors. Power consumption is as low as 120 µA@3.3V when operating in duty-cycle mode with the PGA disabled. The SSP1120 is offered in a TSSOP-16 package and is specified over a temperature range of –40°C to +125°C.
