DS3911

Temperature-Controlled, Nonvolatile,

I C Quad DAC

General Description

Features

The DS3911 is a quad, 10-bit delta-sigma output, nonvol-

atile (NV) controller that features an on-chip temperature

sensor and associated analog-to-digital converter (ADC).

The integrated temperature sensor indexes the up to

2NC resolution NV lookup tables (LUTs), encompassing

a -40NC to +100NC temperature range. The LUT directly

drives the delta-sigma digital-to-analog converter (DAC)

outputs. This flexible LUT-based architecture allows the

device to provide a temperature-compensated DAC out-

put with arbitrary slope. Programming is accomplished

S Four 10-Bit Delta-Sigma Outputs

S On-Chip Temperature Sensor and ADC

S Four Temperature-Indexed LUTs, Up to 2NC

Resolution

S I C-Compatible Serial Interface

S Address Pins Allow Up to Four DS3911s to Share

the Same I C Bus

S 2.8V to 5.5V Digital Supply

S -40NC to +100NC Operating Temperature Range

S 3mm x 5mm, 14-Pin TDFN Package

by an I C-compatible interface that operates at speeds

of up to 400kHz.
