Description

The AX3515J12A is a precision, quad, single-pole single-throw (SPST) analog switch. It belongs to the MAX351/MAX352/MAX353 series, with the AX3515J12A specifically having four normally closed (NC) switches. These switches offer low on resistance (<35Ω) and are guaranteed to match within 2Ω between channels. The AX3515J12A analog switch also has low leakage (<250pA at +25°C and <6nA at +85°C) and fast switching characteristics (turn-on time <175ns and turn-off time <145ns).

Comparison

The AX3515J12A analog switch offers several advantages such as low on resistance, guaranteed matching between channels, and flat on resistance over the signal range. It also has low leakage and fast switching characteristics. However, it is important to note that it operates within a specific voltage range (+10V to +30V for single-supply and ±4.5V to ±20V for bipolar-supply) and has a limited compatibility with TTL/CMOS-logic. Additionally, it has a rail-to-rail analog signal handling capability.
