TM7705 from TM Shenzhen Titan Micro Elec, in a SOIC-16. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SCLK | input | Schmitt logic input for serial clock; applies external serial clock to access TM7705 serial data in continuous or non-continuous mode. |
| 2 | MCLK IN | input | Master clock input for converter; accepts crystal, resonator, or external CMOS-compatible clock signal with frequency range 500kHz to 5MHz. |
| 3 | MCLK OUT | output | Master clock output connected with MCLK IN for crystal/resonator oscillator operation; provides inverted clock if external clock applied; disableable via CLK DIS bit. |
| 4 | CS | input | Active-low chip select input; selects TM7705 for three-wire serial interface operation; can serve as frame synchronization in multi-device systems. |
| 5 | RESET | input | Active-low reset input; resets control logic, interface logic, calibration coefficients, digital filter, and analog modulator to power-up state. |
| 6 | AIN2(+) | input | Positive input of fully-differential analog input channel 2; accepts differential signals relative to AIN2(-) from GND-30mV to VDD+30mV. |
| 7 | AIN1(+) | input | Positive input of fully-differential analog input channel 1; accepts differential signals relative to AIN1(-) from GND-30mV to VDD+30mV. |
| 8 | AIN1(-) | input | Negative input of fully-differential analog input channel 1; serves as reference point for differential input measurements; absolute voltage -0.3V to VDD+0.3V. |
| 9 | REF IN(+) | input | Positive differential reference input; must exceed REF IN(-); difference voltage 1V minimum to 3V maximum depending on VDD and specified performance. |
| 10 | REF IN(-) | input | Negative differential reference input; accepts voltages between GND and VDD provided REF IN(+) exceeds this voltage. |
| 11 | AIN2(-) | input | Negative input of fully-differential analog input channel 2; serves as reference point for differential input measurements; absolute voltage -0.3V to VDD+0.3V. |
| 12 | DRDY | output | Logic output; pulses low when new output word available in data register; returns high during register update (minimum 500×tCLKIN); indicates calibration completion. |
| 13 | DOUT | output | Serial data output from internal shift register; delivers conversion results and register contents selected by communication register bits RS2-RS0. |
| 14 | DIN | input | Serial data input to internal shift register; accepts configuration data routed to registers selected by communication register bits RS2-RS0. |
| 15 | VDD | power_in | Power supply voltage input; operating range +2.7V to +3.3V or +4.75V to +5.25V for specified performance; maximum ratings -0.3V to +7V. |
| 16 | GND | power_in | Ground reference; internal circuit ground potential reference point; provides system ground return path. |
