TSH80ID Equivalent & Substitute Parts

Part Overview

The TSH80ID is a general-purpose operational amplifier manufactured by STMicroelectronics, housed in an 8-SOIC surface-mount package. This device is classified as obsolete, indicating discontinued production and limited availability for new designs. The TSH80ID features rail-to-rail output capability with a gain-bandwidth product of 65 MHz and operates across a 4.5 V to 12 V supply range. Due to its obsolete status, equivalent substitute parts from active manufacturers are necessary for ongoing production, maintenance, and new application development.

Substitute Part Grouping Explanation

Substitution of the TSH80ID is determined by strict electrical and mechanical compatibility across the following critical parameters:

Mechanical Compatibility: All substitute parts must use the 8-SOIC (0.154", 3.90mm Width) surface-mount package to ensure direct board-level compatibility without layout modifications.

Electrical Compatibility: Substitute parts must maintain rail-to-rail output capability and single-circuit configuration. The supply voltage range must encompass or exceed the TSH80ID operating range of 4.5 V to 12 V. Input bias current, input offset voltage, slew rate, and output current drive capability are secondary parameters that determine performance equivalence but do not preclude substitution if the primary mechanical and functional requirements are met.

Compliance Requirements: All substitute parts must maintain ROHS3 compliance and MSL 1 rating to ensure regulatory and manufacturing process compatibility.

The identified substitute parts—AD8051ARZ, AD8051ARZ-REEL, AD8051ARZ-REEL7 (Analog Devices Inc.), and LMH6642MA/NOPB, LMH6642MAX/NOPB (Texas Instruments)—satisfy these criteria and are classified as active products with current manufacturing availability.
