FEATURES

DESCRIPTIO

The LTC^®1821 is a parallel input 16-bit multiplying voltage

output DAC that operates from analog supply voltages of

±5V up to ±15V. INL and DNL are accurate to 1LSB over the

industrial temperature range in both unipolar 0V to 10V and

bipolar±10Vmodes.Precise16-bitbipolar±10Voutputsare

achieved with on-chip 4-quadrant multiplication resistors.

The LTC1821 is available in a 36-lead SSOP package and is

specified over the industrial temperature range.

■

2µs Settling to 0.0015% for 10V Step

■

1LSB Max DNL and INL Over Industrial

Temperature Range

■

On-Chip 4-Quadrant Resistors Allow Precise 0V to

10V, 0V to –10V or ±10V Outputs

■

Low Glitch Impulse: 2nV•s

■

Low Noise: 13nV/√Hz

■

36-Lead SSOP Package

■

Power-On Reset

Thedeviceincludesaninternaldeglitchercircuitthatreduces

the glitch impulse to less than 2nV•s (typ). The LTC1821

settles to 1LBS in 2µs with a full-scale 10V step. The

combinationoffast,precisesettlingandultralowglitchmake

the LTC1821 ideal for precision industrial control applica-

tions.

■

Asynchronous Clear Pin

LTC1821: Reset to Zero Scale

LTC1821-1: Reset to Midscale

APPLICATIO S

The asynchronous CLR pin resets the LTC1821 to zero scale

and resets the LTC1821-1 to midscale.
