The Siliconix LD110/111(A)  (P/N 156-0476-00,156-0476-00,156-1268-00) is a 3½ digit A/D converter monolithic integrated circuit chip set from the mid-1970s.

The LD110 (156-0476-00) is a PMOS digital processor that combines counting, storage, and data multiplexing functions.

The LD111 (156-0477-00) is an analog processor in mixed bipolar and MOSFET technology.

The LD111A (156-1268-00) is a pin-compatible update of the earlier LD111. It eliminated the need for an integrator clamp zener, and offered improved linearity, noise and temperature stability,

Used in

  • DM502 – U335 (LD110) and U290 (LD111)
  • DM502A – A15U1311 (LD110) and A15U1461 (LD111A)
  • DM505 – A10U1201 (LD111A) and A10U1303 (LD110)
