TSV624IPT Equivalent & Substitute Parts
Part Overview
The TSV624IPT is a CMOS four-circuit rail-to-rail amplifier manufactured by STMicroelectronics in a 14-TSSOP surface mount package. This device is classified as a linear amplifier and is currently in active product status. The TSV624IPT is designed for low-power applications requiring quad operational amplifier functionality with rail-to-rail output capability.
Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be achieved within the specified parameter ranges. Alternative components may be required due to inventory availability, packaging format preferences, or specific application performance requirements while maintaining functional compatibility.

Engineering Selection Recommendations
AD8544ARUZ and AD8544ARUZ-REEL
The AD8544ARUZ series from Analog Devices provides the closest electrical performance match to the TSV624IPT. Both devices share identical operating temperature range (-40°C to 125°C), supply voltage span (2.7V to 5.5V maximum), and 14-TSSOP packaging. The AD8544 series exhibits superior input offset voltage (1 mV versus 4 mV) and lower supply current (45 µA versus 29 µA). These devices are ROHS3 compliant with MSL 1 rating. The AD8544ARUZ-REEL variant provides cut tape and Digi-Reel packaging format.
AD8604ARUZ, AD8604DRUZ, and AD8604DRUZ-REEL
The AD8604 series (DigiTrim® technology) offers enhanced performance with superior input offset voltage (80 µV to 1.3 mV), higher slew rate (6 V/µs), and increased gain bandwidth product (8.4 MHz). These devices maintain full operating temperature range compatibility (-40°C to 125°C) and identical 14-TSSOP packaging. Supply current is higher at 750 µA. All variants are ROHS3 compliant with MSL 1 rating.
AD8608ARUZ and AD8608ARUZ-REEL
The AD8608 series (DigiTrim® technology) provides the highest performance specifications with 5 V/µs slew rate, 10 MHz gain bandwidth product, and 80 mA output current per channel. Operating temperature range is -40°C to 125°C with identical 14-TSSOP packaging. Supply current is 1 mA per channel. Both tube and cut tape/Digi-Reel packaging options are available. ROHS3 compliant with MSL 1 rating.
AD8534ARUZ and AD8534ARUZ-REEL
The AD8534 series offers higher performance (5 V/µs slew rate, 3 MHz gain bandwidth product) but operates at reduced maximum temperature (-40°C to 85°C). This temperature limitation restricts use in applications requiring the full -40°C to 125°C range. Both tube and cut tape/Digi-Reel packaging formats are available. ROHS3 compliant with MSL 1 rating.
AD8648ARUZ
The AD8648 provides the highest performance specifications (11 V/µs slew rate, 24 MHz gain bandwidth product, 120 mA output current per channel) with full operating temperature range (-40°C to 125°C). Supply current is 1.5 mA per channel. This device is suitable for applications requiring maximum bandwidth and slew rate performance. ROHS3 compliant with MSL 1 rating. Available in tube packaging.
Packaging Format Considerations
The TSV624IPT is supplied in Tape & Reel (TR) format. Substitute parts are available in Tube, Cut Tape (CT) & Digi-Reel®, or Cut Tape & Digi-Reel® formats. Selection should account for assembly process requirements and tape specifications.
Frequently Asked Questions (FAQ)
Q: Can the AD8534ARUZ substitute for the TSV624IPT in all applications?
A: The AD8534ARUZ is electrically compatible with the TSV624IPT in the 14-TSSOP package with rail-to-rail output. However, the AD8534ARUZ operates at a maximum temperature of 85°C, while the TSV624IPT operates to 125°C. Applications requiring the full -40°C to 125°C temperature range must use alternative substitutes such as the AD8544ARUZ, AD8604 series, AD8608 series, or AD8648ARUZ.
Q: What is the difference between AD8604ARUZ and AD8604DRUZ?
A: Both devices are identical in electrical performance and packaging. The primary difference is the input offset voltage specification: AD8604ARUZ specifies 80 µV while AD8604DRUZ specifies 1.3 mV. Both are ROHS3 compliant with MSL 1 rating and operate across -40°C to 125°C.
Q: Are the cut tape and Digi-Reel variants electrically equivalent to tube-packaged versions?
A: Yes. The cut tape (CT) & Digi-Reel® variants (identified by -REEL suffix) are electrically identical to their tube-packaged counterparts. The difference is packaging format only. Selection depends on assembly equipment compatibility and tape specifications.
Q: Which substitute part offers the lowest power consumption?
A: The TSV624IPT itself offers the lowest supply current at 29 µA. Among the substitute parts, the AD8544ARUZ series provides the next lowest supply current at 45 µA per channel. Higher-performance devices (AD8604, AD8608, AD8648 series) consume 750 µA to 1.5 mA per channel.
Q: Can I use the AD8648ARUZ as a direct replacement for the TSV624IPT?
A: The AD8648ARUZ is mechanically and electrically compatible with the TSV624IPT in the 14-TSSOP package. However, the AD8648ARUZ exhibits significantly higher performance specifications (11 V/µs slew rate, 24 MHz gain bandwidth product) and higher supply current (1.5 mA per channel). Applications designed for the TSV624IPT's lower bandwidth and power consumption may not require these enhanced specifications.
Q: What is the minimum supply voltage for substitute parts?
A: The TSV624IPT operates at a minimum supply voltage of 1.5 V. All substitute parts listed operate at a minimum of 2.7 V. Applications requiring operation below 2.7 V cannot use these substitute parts.
Q: Are all substitute parts ROHS3 compliant?
A: Yes. All substitute parts listed (AD8534, AD8544, AD8604, AD8608, and AD8648 series) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the TSV624IPT compliance status.
Q: Which substitute provides the best balance of performance and power consumption?
A: The AD8544ARUZ series provides a balanced profile with moderate performance improvement (0.92 V/µs slew rate, 1 MHz gain bandwidth product) and minimal power increase (45 µA supply current). This device maintains full operating temperature range compatibility (-40°C to 125°C) and identical 14-TSSOP packaging.
