Upgrade Your Microcontroller ADC to True 12-Bit Performance
Design Note DN463
by Guy Hoover
Introduction
Many 8-bit and 16-bit microcontrollers feature 10-bit
internal ADCs. A few include 12-bit ADCs, but these often
have poor or nonexistent AC speciп¬Ѓcations, and certainly
lack the performance to meet the needs of an increasing
number of applications. The LTC В®2366 and its slower
speed versions offer a high performance alternative, as
shown in the AC speciп¬Ѓcations in Table 1. Compare these
guaranteed speciп¬Ѓcations with the ADC built into your
current microcontroller.
This familyвЂ™s DC speciп¬Ѓcations are equally impressive. INL
and DNL are guaranteed to be less than В±1LSB. Operating
from a single 2.5V, 3V or 3.3V supply, the current draw
on these parts is a maximum of 4mA during a conversion. This can be reduced to less than 1ОјA by placing
the part into SLEEP mode during periods of inactivity,
which greatly reduces the average supply current at lower
sample rates.

0.1ОјF These ADCs are available in tiny 6-lead and 8-lead TSOT23 packages. The 8-lead devices have adjustable VREF
and OVDD pins. The adjustable VREF pin allows the input …

DESIGN FEATURES Simple, Precise Instrumentation
Ampliп¬Ѓer Features Digitally
Programmable Gains from 1 to 4096
by Michael Kultgen Introduction
The LTCВ®6915 is the simplest, most
precise way to obtain digitally programmable voltage gain. Any system
which needs accurate ampliп¬Ѓcation of
small differential voltages and rejection of large common mode signals will
beneп¬Ѓt from the LTC6915.
The LTC6915 is an evolution of the
LTC2053, a precision rail-to-rail input
and output, zero-drift instrumentation
ampliп¬Ѓer. Due to the ampliп¬ЃerвЂ™s very
low DC errors, very high levels of gain
can be taken in a single stage. The
LTC2053 uses external resistors to set
the gain; the LTC6915 uses a serial
port or a parallel port to select internal
resistors, and therefore select the gain.
The gain can be programmed to 0, 1, 2,
4, 8, 16, 32, 64, 128, 256, 512, 1024,
2048, or 4096. Programmable gain
increases the dynamic range of any …
