Introduction

AI Translation

The OPAx188-Q1 op amp family uses TI's proprietary zero-drift technology to deliver low offset voltage (25μV maximum) with near-zero drift over time and temperature. This high-precision, low quiescent current miniature amplifier family provides high input impedance and rail-to-rail output swing to within 15mV of the supply rails. The input common-mode range includes the negative supply rail. Single or dual supply operation is supported from 4V to 36V (±2V to ±18V). The OPA188-Q1 and OPA2188-Q1 are both available in the VSSOP-8 package. The single-channel version (OPA188-Q1) is fully rated over an operating temperature range of -40°C to +125°C, while the dual-channel version (OPA2188-Q1) is fully rated over -40°C to +105°C. The OPAx188-Q1 op amp family combines low temperature drift with excellent overall performance, making these devices ideal for many precision applications. The low temperature drift of only 0.085μV/°C provides stability across the full temperature range. In addition, the devices deliver excellent overall performance with high CMRR, PSRR, and AOL. The OPAx188-Q1 devices are part of a zero-drift, low-power, rail-to-rail output op amp family. These devices operate from 4V to 36V, are unity-gain stable, and are suited for a wide range of general-purpose applications. The zero-drift architecture provides ultralow input offset voltage with near-zero input offset voltage drift over temperature and time. This architecture also delivers excellent AC performance, including ultralow broadband noise and zero flicker noise.
