TC514COI

Microchip Tech · Analog To Digital Converters (ADCs) · SOIC-28-300mil

TC514COI from Microchip Tech, in a SOIC-28-300mil. 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 VOUT- power_out Negative power supply converter output and reservoir capacitor connection, which can power other devices needing a negative bias voltage.
2 CINT passive Integrator output and integrator capacitor connection.
3 CAZ passive Auto-zero input and connection for the auto-zero capacitor.
4 BUF output Buffer output; the table also labels this pin as the integrator capacitor connection.
5 ACOM passive Analog common, grounded in most applications; ACOM and the input common (VIN- or CHn-) should be within the analog common mode range (CMR).
6 CREF- passive Negative reference capacitor connection.
7 CREF+ passive Positive reference capacitor connection.
8 VREF- power_in External voltage reference negative connection.
9 VREF+ power_in External voltage reference positive connection.
10 CH4- input Negative analog input for MUX channel 4.
11 CH3- input Negative analog input for MUX channel 3.
12 CH2- input Negative analog input for MUX channel 2.
13 CH1- input Negative analog input for MUX channel 1.
14 NC unconnected No TC514 function is assigned to this pin in the pin function table; the excerpt gives no assignment for it.
15 CH4+ input Positive analog input for MUX channel 4.
16 CH3+ input Positive analog input for MUX channel 3.
17 CH2+ input Positive analog input for MUX channel 2.
18 CH1+ input Positive analog input for MUX channel 1.
19 A1 input Multiplexer channel select MSB; with A0 selects channel 1 (00) through channel 4 (11).
20 A0 input Multiplexer channel select LSB; with A1 selects channel 1 (00) through channel 4 (11).
21 B input Converter phase control LSB; with A selects integrator zero (00), auto-zero (01), integrate (10) or de-integrate (11).
22 A input Converter phase control MSB; works with B to set the four conversion phases.
23 CMPTR output Zero-crossing comparator output, high when integrating a positive input and low for a negative input; a high-to-low transition marks the end of de-integrate.
24 OSC input Oscillator control input; the negative supply converter normally runs at 100 kHz and can be slowed by an external capacitor to VDD.
25 VDD power_in Positive power supply connection.
26 CAP+ passive Negative power supply converter capacitor (+) connection.
27 DGND power_in Digital ground.
28 CAP- passive Negative power supply converter capacitor (-) connection.
