LMV762MA

LMV762MA Description

The LMV762MA from National Semiconductor is a high-performance, general-purpose dual comparator designed for precision applications in low-voltage systems. Packaged in an 8-SOIC surface-mount format, this IC operates over a 2.7V to 5V supply range, making it ideal for battery-powered and portable electronics. With an ultra-low input offset voltage of 0.2mV (max) at 5V and minimal input bias current of 50pA (max), the LMV762MA ensures high accuracy in signal detection and conditioning. Its 700µA (max) quiescent current balances power efficiency with speed, featuring a 225ns (max) propagation delay for responsive performance.

LMV762MA Features

• Exceptional Noise Immunity: 100dB CMRR and 110dB PSRR minimize errors from common-mode noise and power supply fluctuations.
• Wide Operating Voltage: Supports 2.7V to 5V single/dual supplies, adaptable to diverse system requirements.
• Low-Power Precision: Combines low offset voltage (0.2mV) and bias current (50pA) with moderate quiescent current (700µA).
• Fast Response: 225ns propagation delay enables quick decision-making in time-critical applications.
• Robust Packaging: 8-SOIC surface-mount design ensures reliability and ease of integration.
