1. TLV2372IDGK Substitution Conclusion The TLV2372IDGK can conditionally substitute for the AD8546ARMZ-R-R7, with significant alterations to system performance and power consumption characteristics. The TLV2372IDGK holds a decisive advantage in dynamic performance, featuring a slew rate (2.1 V/µs) and gain bandwidth product (3 MHz) that are 26 times and 15 times greater than the original part, respectively. It significantly outperforms the AD8546 in applications involving high-speed signals or requiring higher closed-loop bandwidth. This performance gain comes at the cost of a substantial increase in quiescent power consumption; its quiescent current (750 µA per channel) is over 40 times that of the original part (18 µA per channel), which is a critical drawback for battery-powered or ultra-low-power designs. Furthermore, its maximum supply voltage (16 V) is slightly lower than the AD8546's (18 V), requiring attention in applications operating near this upper limit. Substitution is only viable in applications where microamp-level current consumption is not critical, but higher signal processing speed is required. If the original design relies on the AD8546's ultra-low quiescent current, the substitution is not feasible.
