1 Features

• Designed for size, cost, and power conscious

applications

• Selectable gain options with integrated reference

buffer

– G = 10 or G = 20 (INA351ABS)

– G = 30 or G = 50 (INA351CDS)

• Space saving ultra-small package options

– 10-pin X2QFN (RUG) – 3 mm2

– 8-pin WSON (DSG) – 4 mm2

– 8-pin SOT23-THN (DDF) – 4.64 mm2

• Optimized performance for 10-bit to 14-bit systems

– CMRR: 95 dB (typ) across all gains

– Offset voltage: 0.2 mV (typ) across all gains

– Gain error (typ):

• 0.015 for G = 10, G = 50

• 0.020 for G = 20, G = 30

• Bandwidth: 100 kHz for G = 10 (typ)

• Drives 500 pF with less than 20 overshoot (typ)

• Optimized quiescent current: 110 μA (typ)

• Shutdown option for power conscious applications

• Supply range: 1.8 V (±0.9 V) to 5.5 V (±2.75 V)

• Specified temperature range: –40°C to 125°C

2 Applications

• Bridge network sensing

• Differential to single-ended conversion

• Weigh scale

• Analog input module

• Flow transmitter

• Wearable fitness and activity monitor

• Blood glucose monitor

• Pressure and temperature sensing

3 Description

INA351 is a selectable-gain instrumentation amplifier

with integrated reference buffer that offers four gain

options across INA351ABS and INA351CDS variants

available in small packages. INA351ABS has gain

options of 10 or 20 and INA351CDS has gain options

of 30 or 50. These gain options can be selected

by toggling the gain select (GS) pin. INA351 is

an excellent choice for bridge-type sensing and for

differential to single-ended conversion applications.

Built with precision matched integrated resistors,

INA351 saves on BOM costs, pick-and-place machine

handling costs, and board space by removing the

need for precise or closely-matched external resistors.

The INA351 can interface directly to low-speed, 10-bit

to 14-bit, analog-to-digital converters (ADC) and is an

excellent choice for replacing discrete implementation

of instrumentation amplifiers built with commodity

amplifiers and discrete resistors.

Designed with the three-amplifier architecture, INA351

is optimized for delivering performance. The device

achieves 86 dB of minimum CMRR and an accurate

0.1 of maximum gain error, along with 1.3 mV

of maximum offset across all gain options, while

consuming just 135 μA of maximum quiescent

current. INA351 has an integrated shutdown option

to turn off the amplifier when idle for additional power

savings in battery powered applications.
