Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SCLK | input | Schmitt-logic serial clock input for accessing TM7707 serial data; may be continuous or non-continuous burst clock. |
| 2 | MCLK IN | input | Master clock input from crystal/resonator or CMOS-compatible external clock, 500kHz to 5MHz. |
| 3 | MCLK OUT | output | Crystal/resonator connection to MCLK IN, or inverted clock output that can drive a CMOS load; can be disabled via CLK DIS bit. |
| 4 | CS | input | Active-low chip select logic input; tie low for three-wire interface or use as frame sync. |
| 5 | RESET | input | Active-low reset input that resets control logic, interface logic, calibration coefficients, digital filter and analog modulator to power-on state. |
| 6 | AIN2(+) | input | Positive input of differential analog input channel 2 on TM7707 (channel 1 input on TM7708). |
| 7 | AIN1(+) | input | Positive input of differential analog input channel 1 on TM7707 (channel 2 input on TM7708). |
| 8 | AIN1(-) | input | Negative input of differential analog input channel 1 on TM7707 (COMMON reference input on TM7708). |
| 9 | REF IN(+) | input | Positive differential reference input; must be greater than REF IN(-) and may be any value between VDD and GND. |
| 10 | REF IN(-) | input | Negative differential reference input; may be any value between VDD and GND provided REF IN(+) is greater. |
| 11 | AIN2(-) | input | Negative input of differential analog input channel 2 on TM7707 (channel 3 input on TM7708). |
| 12 | DRDY | output | Active-low logic output indicating a new output word is available in the data register; returns high after a read completes and also indicates calibration completion. |
| 13 | DOUT | output | Serial data output from the on-chip output shift register (communication, clock or data register contents). |
| 14 | DIN | input | Serial data input to the on-chip input shift register, routed to the setup, clock or communication register. |
| 15 | VDD | power_in | Supply voltage, +2.7V to +5.25V. |
| 16 | GND | power_in | Ground reference point for internal circuitry. |
