TLV1504IPWR from Texas Instruments, 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 | SDO | tri_state | The 3-state serial output carries the A/D result MSB first and is held high-impedance while CS is high and until the MSB is presented. |
| 2 | SDI | input | Serial data input, MSB (D15) first, whose first four bits are decoded as one of the commands (12 commands on the TLV1504) and is latched on SCLK edges. |
| 3 | SCLK | input | Input serial clock from the host processor that clocks SDI into the input register and may also serve as the source of the conversion clock. |
| 4 | EOC/(INT) | output | Programmed as EOC, it goes low at the end of sampling until conversion is complete and data are ready; programmed as INT, its falling edge indicates data are ready for output. |
| 5 | VCC | power_in | Positive supply voltage; the device operates from a single 2.7-V to 5.5-V power supply. |
| 6 | A0 | input | Analog signal input, internally multiplexed, with a driving source impedance that should be less than or equal to 1 kΩ (use CSTART or long sampling for higher impedance). |
| 7 | A1 | input | Analog signal input, internally multiplexed, with a driving source impedance that should be less than or equal to 1 kΩ (use CSTART or long sampling for higher impedance). |
| 8 | A2 | input | Analog signal input, internally multiplexed, with a driving source impedance that should be less than or equal to 1 kΩ (use CSTART or long sampling for higher impedance). |
| 9 | A3 | input | Analog signal input, internally multiplexed, with a driving source impedance that should be less than or equal to 1 kΩ (use CSTART or long sampling for higher impedance). |
| 10 | CSTART | input | Controls the start of sampling of the selected analog channel, with the rising edge (when CS is high) starting conversion; tie to VCC if not used. |
| 11 | GND | power_in | Ground return for the internal circuitry; all voltage measurements are referenced to GND. |
| 12 | PWDN | input | When held at logic zero, the analog and reference circuits are powered down, and the device restarts via CS, FS, or CSTART after PWDN returns to logic one. |
| 13 | FS | input | DSP frame-sync input that indicates the start of a serial data frame; tie to VCC if not used. |
| 14 | REFM | input | External reference input or internal reference decoupling pin; tie to analog ground if the internal reference is used. |
| 15 | REFP | input | External reference input or internal reference decoupling pin; with an external reference, the maximum input range is the voltage between REFP and REFM, with 10 µF and 0.1 µF shunt capacitors recommended. |
| 16 | CS | input | Chip select; a high-to-low transition resets the internal 4-bit counter, enables SDI, and takes SDO out of 3-state. |
