Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | A1 | input | MSB (bit 1) digital input; noninverting, TTL and CMOS compatible with VIH ≥ 2 V, VIL ≤ 0.8 V; high-level input current 0 to 0.040 mA. |
| 2 | A2 | input | Bit 2 digital input; noninverting TTL/CMOS compatible; low-level input current −0.003 to −0.8 mA. |
| 3 | A3 | input | Bit 3 digital input; noninverting TTL/CMOS compatible. |
| 4 | A4 | input | Bit 4 digital input; noninverting TTL/CMOS compatible. |
| 5 | A5 | input | Bit 5 digital input; noninverting TTL/CMOS compatible. |
| 6 | A6 | input | Bit 6 digital input; noninverting TTL/CMOS compatible. |
| 7 | A7 | input | Bit 7 digital input; noninverting TTL/CMOS compatible. |
| 8 | A8 | input | LSB (bit 8) digital input; noninverting TTL/CMOS compatible. |
| 9 | GND | power_in | Analog/digital ground reference (0 V); return path for output current load resistor. |
| 10 | VREF- | input | Negative reference amplifier input (pin 15 in DIP); a resistor to a negative voltage enables bipolar reference operation; bias current I15 = −1 to −3 µA. |
| 11 | VREF+ | input | Positive reference amplifier input (pin 14 in DIP); reference current I14 must always flow into this pin; full-scale set by VREF/R14 = 2 mA, range 1.9 to 2.1 mA. |
| 12 | VCC | power_in | Positive supply voltage; operating range 4.5 V to 5.5 V, absolute maximum +18 VDC; ICC = 2.3 to 22 mA (all bits low). |
| 13 | NC | unconnected | No internal connection; floating this pin does not affect converter speed or power dissipation. |
| 14 | IO | output | Full-scale output current (pin 4 in DIP); range 0 to 2.0 mA (VEE = −5 V) or 0 to 4.2 mA (VEE ≤ −8 V); output voltage compliance −0.55 V to +0.4 V at VEE = −5 V, −5.0 V to +0.4 V at VEE < −10 V. |
| 15 | VEE | power_in | Negative supply voltage; operating range −4.5 V to −16.5 V, absolute maximum −18 VDC; IEE = −4.3 to −13 mA (all bits low). |
| 16 | COMP | passive | Reference amplifier compensation node (pin 16 in DIP); connect capacitor to VEE or GND to ensure phase margin: 15 pF min for R14 = 1 kΩ, 37 pF for 2.5 kΩ, 75 pF for 5 kΩ. |
