PRODUCTION DATA.
PIN | TYPE(1) | DESCRIPTION | |
---|---|---|---|
NO. | NAME | ||
1 | +OUT AUX | O | Auxiliary positive output |
2 | −OUT AUX | O | Auxiliary negative output |
3, 4 | VCC | P | Analog power supply |
5, 8 | GND | G | Ground, electrically connected to the WQFN heat sink |
6 | +IN | I | Positive input |
7 | –IN | I | Negative input |
9 | CS | I | Serial chip select (SPI interface, active low): While this signal is asserted SCLK is used to accept serial data present on SDIO and to source serial data on SDIO. When this signal is de-asserted, SDIO is ignored and SDIO is in TRI-STATE mode. |
10 | SDIO | I/O | Serial data-in or data-out (SPI interface): Serial data are shifted into the device (8 bit command and 16 bit data) on this pin while CS signal is asserted during Write operation. Serial data are shifted out of the device on this pin during a read operation while CS signal is asserted. At other times, and after one complete Access Cycle (24 bits, see Figure 54 and Figure 55), this input is ignored. This output is in TRI-STATE mode when CS is de-asserted. This pin is bi-directional. |
11 | SCLK | I | Serial clock (SPI interface): Serial data are shifted into and out of the device synchronous with this clock signal. SCLK transitions with CS de-asserted are ignored. SCLK must be stopped when not required to minimize digital crosstalk. |
12 | VDD | P | Digital power supply |
13 | VCM | I | Input from ADC to control main output CM |
14 | −OUT | O | Main negative output |
15 | +OUT | O | Main positive output |
16 | VCM_AUX | I | Input to control auxiliary output CM |
