The Texas Instruments PGA281AIPWR is a high-precision instrumentation amplifier featuring digitally controllable gain and signal-integrity test capabilities. This device utilizes proprietary autozeroing techniques to achieve low offset voltage, near-zero offset and gain drift, excellent linearity, and minimal 1/f noise.
Key electrical specifications include a supply voltage range of 10V to 36V, a bandwidth at Acl of 6 MHz, and a maximum gain of 42 dB. It boasts a low offset voltage of 5 µV at G = 128 and a gain drift of only 0.5 ppm/°C. The amplifier offers a wide input range of ±15.5 V at ±18 V supply and provides binary gain steps from 128 V/V down to 1/8 V/V.
Designed for high-performance applications, the PGA281 provides excellent common-mode rejection (CMRR) of 140 dB and superior common-mode rejection of greater than 110 dB at G = 1 over a wide frequency range. It also features high input impedance and very low 1/f noise.
The PGA281AIPWR is available in a compact TSSOP-16 package, measuring 32 mm² (5 mm × 6.4 mm), making it suitable for space-constrained designs. Its operating temperature range is -40°C to 125°C.
