Engineering Selection Recommendations
LMV823IST (STMicroelectronics)
The LMV823IST is an active general-purpose dual-channel amplifier with rail-to-rail output in a 10-MiniSO package. This device maintains full compatibility with the TLV2773IDGS footprint and supply voltage specifications. The LMV823IST carries AEC-Q100 automotive qualification, indicating enhanced reliability screening. RoHS3 compliance and MSL Level 1 rating are confirmed. The operating temperature range extends to 125°C, matching the original device. This substitute is suitable for applications where automotive-grade qualification and active product status are advantageous.
MAX4327EUB+ (Analog Devices Inc./Maxim Integrated)
The MAX4327EUB+ is an active general-purpose dual-channel amplifier with rail-to-rail output in a 10-uMAX/uSOP package. This device is compatible with the TLV2773IDGS footprint and supply voltage specifications. RoHS3 compliance and MSL Level 1 rating are confirmed. The operating temperature range is -40°C to 85°C, which is narrower than the original device. This substitute is suitable for applications operating within the -40°C to 85°C temperature window and where the extended supply voltage range (up to 6.5V) provides design flexibility.
MAX4338EUB+ and MAX4338EUB+T (Analog Devices Inc./Maxim Integrated)
The MAX4338EUB+ and MAX4338EUB+T are active general-purpose dual-channel amplifiers with rail-to-rail output in 10-uMAX/uSOP packages.

The MAX4338EUB+T is supplied in Tape & Reel packaging, while the MAX4338EUB+ is supplied in Tube packaging. These substitutes are suitable for applications operating within the -40°C to 85°C temperature window and where higher output current capability (110 mA per channel) is beneficial.
Frequently Asked Questions (FAQ)
Q: Can the LMV823IST replace the TLV2773IDGS in all applications?
A: The LMV823IST meets the mandatory compatibility criteria: dual-channel configuration, rail-to-rail output, compatible 10-pin TFSOP/MSOP footprint, supply voltage range 2.5V to 5.5V, and operating temperature range -40°C to 125°C. However, performance parameters differ. The LMV823IST has lower slew rate (1.9 V/µs vs. 10.5 V/µs) and higher input offset voltage (3.5 mV vs. 700 µV). Applications sensitive to slew rate or offset voltage specifications must evaluate compatibility on a case-by-case basis.
Q: What is the difference between MAX4338EUB+ and MAX4338EUB+T?
A: Both devices are electrically identical with the same performance specifications. The primary difference is packaging: MAX4338EUB+ is supplied in Tube packaging, while MAX4338EUB+T is supplied in Tape & Reel (TR) packaging. Selection depends on production volume and assembly line requirements.
Q: Why does the MAX4327EUB+ have a maximum supply voltage of 6.5V while the TLV2773IDGS is limited to 5.5V?
A: The MAX4327EUB+ is specified for operation up to 6.5V maximum supply voltage. However, when substituting for the TLV2773IDGS in existing designs, the supply voltage should remain within the original specification range (2.5V to 5.5V) unless the circuit design is explicitly modified to accommodate the extended range.
Q: Are all substitute parts RoHS3 compliant?
A: Yes. All substitute parts listed—LMV823IST, MAX4327EUB+, MAX4338EUB+, and MAX4338EUB+T—are confirmed RoHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating, matching the original TLV2773IDGS specifications.
Q: What is the impact of the narrower operating temperature range in the MAX4327EUB+ and MAX4338EUB+ devices?
A: The MAX4327EUB+ and MAX4338EUB+ are specified for -40°C to 85°C operation, compared to the TLV2773IDGS range of -40°C to 125°C. Applications requiring operation above 85°C must use the LMV823IST, which maintains the full -40°C to 125°C range. For applications operating within -40°C to 85°C, the narrower range does not present a limitation.
Q: Can I use these substitutes interchangeably in production?
A: All substitute parts share the same 10-pin TFSOP/MSOP footprint and are pin-compatible with the TLV2773IDGS. However, electrical performance parameters vary. Production changeover requires validation that the substitute part meets the specific performance requirements of the application, including slew rate, gain bandwidth product, input offset voltage, and output current specifications.
Q: Which substitute offers the best low-power performance?
A: The LMV823IST offers the lowest supply current at 300 µA per channel (compared to 1 mA for the TLV2773IDGS). This makes the LMV823IST the preferred choice for battery-powered or low-power applications where supply current minimization is critical.
Q: Is the LMV823IST automotive-qualified?
A: Yes. The LMV823IST carries AEC-Q100 automotive qualification, indicating it has undergone enhanced reliability screening and testing protocols. This qualification is beneficial for automotive and industrial applications requiring higher reliability assurance.
