INA126UA/2K5 Texas Instruments 仪表放大器 Micropower Single & Dual Versions

1 Features 3 Description

1 The INA126 and INA2126 are precision • Low Quiescent Current: 175 μA/channel

instrumentation amplifiers for accurate, low noise

• Wide Supply Range: ±1.35 V to ±18 V differential-signal acquisition. Their two-op-amp

• Low Offset Voltage: 250-μV Maximum design provides excellent performance with low

• Low Offset Drift: 3-μV/°C Maximum quiescent current (175 μA/channel). Combined with a

wide operating voltage range of ±1.35 V to ±18 V,

• Low Noise: 35 nV/√Hz makes the INAx126 ideal for portable instrumentation

• Low Input Bias Current: 25-nA Maximum and data acquisition systems.

• 8-Pin PDIP, SOIC, VSSOP Surface-Mount Dual: Gain can be set from 5 V/V to 10000 V/V with a

16-Pin PDIP, SOIC, SSOP single external resistor. Laser-trimmed input circuitry

provides low offset voltage (250-μV maximum), low 2 Applications offset voltage drift (3-μV/°C maximum), and excellent

common-mode rejection. • Industrial Sensor Amplifiers: Bridges, RTDs,

Thermocouples Single version package options include 8-pin plastic

• Physiological Amplifiers: ECGs, EEGs, EMGs PDIP, SOIC-8, and fine-pitch VSSOP-8 surfacemount.

Dual version is available in 16-pin plastic • Multi-Channel Data Acquisition PDIP, SOIC-8, and the space-saving, fine-pitch

• Portable, Battery-Operated Systems SSOP-16 surface-mount. All are specified for the

–40°C to +85°C industrial temperature range.
