This document is the AD8508 technical specification sheet, which introduces the characteristics of AD8508, including PSRR, CMRR, supply current, supply range, input and output range, output offset voltage, input bias current, etc.
The AD8508 is a quad micropower operational amplifier designed for battery‑powered applications. It features rail‑to‑rail input and output, very low supply current, and excellent power‑supply rejection and common‑mode rejection ratios.
Key specifications include PSRR of 100 dB minimum, CMRR up to 105 dB typical, input bias current as low as 1 pA, and operation from 1.8 V to 5 V in a 14‑lead TSSOP package. The device is rated for an operating temperature range of –40 °C to +125 °C.
| Power Supply Rejection Ratio (PSRR) | 100 dB minimum |
|---|---|
| Input Bias Current | 1 pA typical |
| Package | 14‑lead TSSOP |
| Short‑Circuit Limit | 55 mA |
The PSRR is 100 dB minimum.
Typical input bias current is 1 pA (maximum 10 pA).
The device is supplied in a 14‑lead TSSOP package.
