MS5614T

Hangzhou Ruimeng Tech · Digital To Analog Converters (DAC) · TSSOP-16

MS5614T from Hangzhou Ruimeng Tech, in a TSSOP-16. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 DVDD power_in Digital power supply; the datasheet limits the AVDD-to-DVDD difference to -2.8 V to +2.8 V (absolute maximum) and gives a digital supply of 2.7 V to 5.5 V in the recommended conditions.
2 PD input Power-down pin; when driven low the chip is shut down.
3 LDAC input When LDAC is high the DAC outputs are not updated; when LDAC is low the DAC outputs are updated.
4 DIN input Serial data input; 16-bit words (4 control bits plus 12 data bits) are shifted in MSB first on the falling edge of SCLK.
5 SCLK input Serial digital clock input, rated up to 20 MHz, with minimum high and low widths of 25 ns.
6 CS input Chip select, active low; the serial interface is only active while CS is low, allowing several devices on one serial bus.
7 FS input Frame synchronization input; serial data is clocked in on its falling edge and the internal DAC updates after 16 bits are transferred or when FS goes high.
8 DGND power_in Digital ground.
9 AGND power_in Analog ground; the datasheet recommends a 0.1 uF ceramic bypass between VDD and AGND placed as close to the chip as possible.
10 REFINCD input Reference voltage input for channels C and D; the input range is 0 V to AVDD-1.5 V, and exceeding AVDD/2 causes output saturation at large codes.
11 OUTD output Analog output of channel D, swinging from 0 V to AVDD-0.4 V with a 10 kΩ load.
12 OUTC output Analog output of channel C, swinging from 0 V to AVDD-0.4 V with a 10 kΩ load.
13 OUTB output Analog output of channel B, swinging from 0 V to AVDD-0.4 V with a 10 kΩ load.
14 OUTA output Analog output of channel A, swinging from 0 V to AVDD-0.4 V with a 10 kΩ load.
15 REFINAB input Reference voltage input for channels A and B; the input range is 0 V to AVDD-1.5 V, and exceeding AVDD/2 causes output saturation at large codes.
16 AVDD power_in Analog power supply; the datasheet gives 4.5 V to 5.5 V for 5 V operation and 2.7 V to 3.3 V for 3 V operation.
