Dual-Channel, Rail-to-Rail I/O Op Amp with Excellent Speed/Power Ratio

The TSV99x and TSV99xA family of single, dual, and quad operational amplifiers from STMicroelectronics offers low voltage operation and rail-to-rail input and output. They are offered in a variety of package styles.

These devices feature an excellent speed/power consumption ratio, offering a 20MHz gain-bandwidth, stable for gains above 4 (100pF capacitive load), while consuming only 1.1mA maximum at 5V.

They also feature an ultra-low input bias current. These characteristics make the TSV99x family ideal for sensor interfaces, battery-supplied and portable applications, as well as active filtering. They are suited for medical instrumentation, wearables, automotive designs and similar sensor interface applications.

Available packages include SOT23-5, DFN8 2×2, DFN6 1.3×1.6×0.55, MiniSO8, SO8, DFN8 2×2, SO14, and TSSOP14. Their operating temperature range is -40 to +125 degrees C, ambient.
