Circuit Description
The LTC6246/LTC6247/LTC6248 have an input and output
signal range that extends from the negative power supply
to the positive power supply. Figure 1 depicts a simplified
schematic of the amplifier. The input stage is comprised
of two differential amplifiers, a PNP stage, Q1/Q2, and an
NPN stage, Q3/Q4 that are active over different common
mode input voltages. The PNP stage is active between
the negative supply to nominally 1.2V below the positive
supply. As the input voltage approaches the positive sup-
ply, the transistor Q5 will steer the tail current, I1, to the
current mirror, Q6/Q7, activating the NPN differential pair
and the PNP pair becomes inactive for the remaining input
commonmoderange.Also,attheinputstage,devicesQ17
to Q19 act to cancel the bias current of the PNP input pair.
When Q1/Q2 are active, the current in Q16 is controlled to
be the same as the current in Q1 and Q2. Thus, the base
current of Q16 is nominally equal to the base current of
the input devices. The base current of Q16 is then mirrored
by devices Q17 to Q19 to cancel the base current of the
input devices Q1/Q2. A pair of complementary common
emitter stages, Q14/Q15, enable the output to swing from
rail-to-rail.

–IN: Inverting Input of Amplifier. Valid input range from V–
to V+.
+IN: Non-Inverting Input of Amplifier. Valid input range
from V– to V+.
V+ : Positive Supply Voltage. Allowed applied voltage
ranges from 2.5V to 5.25V when V– = 0V.
V–:NegativeSupplyVoltage.Typically0V.Thiscanbemade
a negative voltage as long as 2.5V ≤ (V+ – V–) ≤ 5.25V.
SHDN: Active Low Shutdown. Threshold is typically 1.1V
referenced to V–. Floating this pin will turn the part on.
OUT: Amplifier Output. Swings rail-to-rail and can typically
source/sink over 50mA of current at a total supply of 5V.
