AK5720VT

Asahi Kasei Microdevices · Pre-ordered Chips · TSSOP-16

AK5720VT from Asahi Kasei Microdevices, 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	VCOM	output	ADC common voltage output at 50%VA, which needs a 0.47µF ceramic capacitor between VCOM and VSS and must not be loaded with any current.
2	RIN	input	Rch single-ended analog input, which should be left open when unused.
3	LIN	input	Lch single-ended analog input, which should be left open when unused.
4	VSS	power_in	Ground pin that must be connected to the analog ground plane.
5	VA	power_in	Analog power supply of 2.7 to 5.5V (typ. 3 or 5V) that sets the analog input range.
6	VD	power_in	Digital power supply of 2.7 to 5.5V (typ. 3 or 5V).
7	GSEL	input	Input gain select where L selects 0dB and H selects +15dB, and it must be fixed to H or L while PDN is H.
8	REGO	output	Regulator output pin, which will be damaged if a voltage higher than 2.5V is applied to it.
9	SDTO	output	Audio serial data output that is held low (VSS) in power-down status.
10	LRCK	bidirectional	Input/output channel clock that is an input in slave mode and fixed to 1fs output in master mode.
11	MCLK	input	Master clock input that must be provided in master mode unless PDN is L.
12	BICK	bidirectional	Audio serial data clock that is an input in slave mode and fixed to 64fs output in master mode.
13	PDN	input	Reset and power-down pin where L resets and powers down the device and H gives normal operation.
14	DIF/TDMI	input	Audio data format select (L: MSB justified, H: I2S) when CKS is in normal mode, or TDM data input when CKS selects TDM mode.
15	FSEL	input	Digital filter select where L selects sharp roll-off and H selects short delay sharp roll-off.
16	CKS	input	Mode select pin set by its connection or external resistor value, with parasitic capacitance that should be less than 20pF.
