ADC128D818CIMT

Texas Instruments · Analog To Digital Converters (ADC) · TSSOP-16

ADC128D818CIMT 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 VREF power_in ADC reference pin: leave unconnected to use the 2.56-V internal VREF (the POR default), or drive with an external voltage between 1.25 V and V+; bypass with 1-µF and 0.1-µF capacitors.
2 SDA bidirectional I2C serial bus bidirectional data line; NMOS open-drain output that requires an external pullup resistor to function properly.
3 SCL input I2C serial bus clock input that requires an external pullup resistor to function properly.
4 GND power_in Ground reference, internally connected to all of the circuitry; all voltages are measured with respect to GND.
5 V+ power_in Power supply input of 3.0 V to 5.5 V; bypass with the parallel combination of 1-µF (electrolytic or tantalum) and 0.1-µF (ceramic) capacitors.
6 INT output Active-low interrupt request output, NMOS open-drain; requires an external pullup resistor to function properly.
7 A0 input Tri-level serial address input that, together with A1, selects one of 9 addresses so that up to 9 devices can share a single I2C bus.
8 A1 input Tri-level serial address input that, together with A0, selects one of 9 addresses so that up to 9 devices can share a single I2C bus.
9 IN7 input Analog input whose full-scale range is set by the internal or external VREF, configurable as single-ended and/or pseudo-differential; absolute maximum voltage is -0.3 V to V+ + 0.3 V.
10 IN6 input Analog input whose full-scale range is set by the internal or external VREF, configurable as single-ended and/or pseudo-differential; absolute maximum voltage is -0.3 V to V+ + 0.3 V.
11 IN5 input Analog input whose full-scale range is set by the internal or external VREF, configurable as single-ended and/or pseudo-differential; absolute maximum voltage is -0.3 V to V+ + 0.3 V.
12 IN4 input Analog input whose full-scale range is set by the internal or external VREF, configurable as single-ended and/or pseudo-differential; absolute maximum voltage is -0.3 V to V+ + 0.3 V.
13 IN3 input Analog input whose full-scale range is set by the internal or external VREF, configurable as single-ended and/or pseudo-differential; absolute maximum voltage is -0.3 V to V+ + 0.3 V.
14 IN2 input Analog input whose full-scale range is set by the internal or external VREF, configurable as single-ended and/or pseudo-differential; absolute maximum voltage is -0.3 V to V+ + 0.3 V.
15 IN1 input Analog input whose full-scale range is set by the internal or external VREF, configurable as single-ended and/or pseudo-differential; absolute maximum voltage is -0.3 V to V+ + 0.3 V.
16 IN0 input Analog input whose full-scale range is set by the internal or external VREF, configurable as single-ended and/or pseudo-differential; absolute maximum voltage is -0.3 V to V+ + 0.3 V.
