Power-On Reset to 0V
Asynchronous Clear to 0V for All Ranges
The LTC
®
1588/LTC1589/LTC1592 are serial input 12-/14-
/16-bit multiplying current output DACs that operates
from a single 5V supply. These SoftSpan
TM
DACs can be
software-programmed for either unipolar or bipolar mode
through a 3-wire SPI interface. In either mode, the voltage
output range can also be software-programmed. Two
output ranges in unipolar mode and four output ranges in
bipolar mode are available.
INL and DNL are accurate to 1LSB over the industrial
temperature range in both unipolar and bipolar modes.
True 16-bit 4-quadrant multiplication is achieved with
on-chip four quadrant multiplication resistors. The
LTC1588/LTC1589/LTC1592 are available in a 16-lead
SSOP package.
These devices include an internal deglitcher circuit that
reduces the glitch impulse to less than 2nV-s (typ).
The asynchronous clear pin resets the LTC1588/LTC1589/
LTC1592 to 0V in unipolar or bipolar mode.

LM46002AQ
Has anyone used this power chip (LM46002AQPWPR)? The design is to output 12V (input wide voltage 3.9-24V). Now it is measured that no matter how much the input is, the output is about 4V, and the FB p...

[Ask TI] Common high-frequency boards have many vias between the upper and lower ground planes. Can you tell me what the benefits are?
[i=s] This post was last edited by dontium on 2015-1-23 13:34 [/i] My initial idea is to eliminate the inductive reactance between the upper and lower layers and some decoupling effect. I don’t know i...

Can I use chipscope to see the waveform if I only have one spatarn-6 board?
I only have a Spatarn 6 board, and I want to use chipscope to observe the waveform of a Verilog counter. Now I set up the project in ISE, and set up the net in the scope inserter, but when I click sta...
