LNDINA333A/B/C

INA333 Footprint Compatible Instrumentation

Amplifiers (INA) use 50% Less Current



Fully differential AC Only (LND

GENERAL DESCRIPTION

FEATURES

The LNDINA333A/B/C are precision instrumentation

amplifiers designed to be footprint compatible with the TI

INA333. Although the LNDINA333 are footprint compatible

they offer similar performance to the INA333 with a 30%

reduction in power consumption (25uA typical and 30uA

maximum vs. 50uA typical and 80uA maximum for the

INA333). The LNDINA333A has a single ended output

replicating the INA333A while the outputs of LNDINA333B/C

are fully differential.



Instrumentation Amplifier

Single ended (LNDINA333A)

Fully differential (LNDINA333B)

Fully differential AC only (LNDINA333C)

+2.7V to +5.5V input range

25μA typ current consumption (INA333, 50μA)

35μA typ current (LNDINA333C)

350kHz typical bandwidth

25μV typical input offset voltage

100dB typical CMRR

100nV/√Hz typical input referred noise

RFI Filtered Inputs

External resistor or programmable gain

Minimum gain setting 100V/V

Input range: GND-0.1V to VDD+0.1V

Output range: GND+0.05V to VDD-0.05V

Low drift: 2μV/°C typical

+/-5pA typical input bias current

10mA short circuit current

8kV ESD Protection (vs. 4kV for INA333)

Temperature range: -40°C to 125°C

Footprint compatible with EPAD DFN-8

If an RG resistor is connected between the RG pins then the

differential current will be set by the external resistor. On the

other hand if the RG inputs remain high impedance then a

pulse on RG/DIG- will cause an internal resistor to decrement

in value, while a pulse on RG/DIG+ will cause the internal

resistor to increment in value. Default is half scale.

The LNDINA333C is an AC only instrumentation amplifier

which has a 5Hz 3dB high pass response. Integrators are

connected between the output and feedback nodes to form a

high pass response as shown in the block diagram below.

The LNDINA333A/B/C features 8kV HBM ESD protection

compared to 4kV with the INA333. The inputs are also RFI

filtered to reduce EMI susceptibility.

The LNDINA333A/B/C is available in a EPAD DFN-8 package

which has a 65°C/W thermal resistance.
