12 bit low-power analog-to-digital conversion chip RS1320
RS1320 is a low-power single channel 12 bit analog-to-digital converter chip with a working voltage support of 2.7V to 5.5V. It supports SPI, QSPI, Microwire, and DSP interfaces, and can be used to achieve digital signal control output analog voltage, restore analog signals, or provide controllable reference voltage. It has a wide range of applications in industrial field data acquisition, various instrument measurement equipment, and analysis equipment.
RS1320 is based on mainstream market products and optimized for key parameters according to user application needs, further reducing linear error, zero code error temperature drift, gain error, and gain error temperature drift. It also optimizes and improves conversion rate while considering low power consumption, shortening output voltage establishment time to meet more application scenarios. Its main parameter characteristics are as follows: Ø Ensure output monotonicity; Built in buffer, rail to rail voltage output; Ø Power on output zero voltage; Low power consumption: 1.17mW (3.6V)/2.94mW (5.5V); Ø INL: - 0.7LSB/+1.2LSB； Ø DNL: - 0.1LSB/+0.2LSB； Ø Zero code error 1.3mV; Ø Full scale error -0.01% FS; Ø Output voltage establishment time 6 μ s @ CL=500pF Ø Supports SPI data interface; Ø Extended industrial temperature range:- 40 ° C~125 ° C.
RS1320 adopts a resistor string architecture design, achieving excellent AC/DC characteristics. Some parameter curves are referenced as follows:
