| Number of taps | 100, 256 |
| Case | 14-TSSOP (0.173\", 4.40mm Width) |
| Resistance | 10k |
| Number of circuits | 2 |
| Temperature coefficient | 750ppm/°C |
| Resistance - wiper (Ohms) | 500 |
The typical temperature coefficient is 750 ppm/°C — not a precision trimmer, but adequate for bias adjustment and calibration in most industrial environments. The wiper resistance is typically 500Ω, which matters at the low end of the range when the wiper is near the B terminal.
Housed in a 14-TSSOP package (4.40 mm width), the part is surface-mount and suited for dense PCB layouts.
It is ROHS3 compliant.
One channel has 100 taps, the other has 256 taps — a mixed resolution that allows fine adjustment on one pot and coarser steps on the other.
The DS1845E-010+ has a 10kΩ resistance; the DS1845E-100 has a 100kΩ resistance. Both share the same 14-TSSOP package, I²C interface, and dual 100/256 tap resolution. The choice depends on the impedance range your circuit needs.
