Overview
The TLV2170IDGKR is a dual-channel operational amplifier from Texas Instruments, part of the TLVx170 family. These amplifiers are designed for cost-sensitive systems and offer a wide range of features that make them suitable for various applications. The TLV2170 operates on a single supply ranging from 2.7 V to 36 V (or ±1.35 V to ±18 V) and is known for its low noise, high common-mode rejection ratio (CMRR), and low quiescent current. The device is EMI-hardened with RFI-filtered inputs, ensuring robust performance in noisy environments.
The TLV2170 is available in an 8-pin VSSOP package, making it compact and suitable for space-constrained designs. It is specified to operate over a temperature range of –40°C to +125°C, making it versatile for different environmental conditions.
