The cross reference tool says that the TLV9051 is a drop-in replacement.

The LMV821-N web page says that the TLV9051 is a "Drop-in replacement with upgraded functionality to the compared device."

Hey Gareth,

Please see the below table for a comparison between the LMV821 and the TLV9051. I checked the page, however, and noticed that the DCK package is out of stock. Could you provide system specs or a circuit so I may help you find a device in stock that meets your system requirements?

► Part Number	LMV821	TLV9051
Channel Count	1	1
Vs Range	2.5V to 5.5V	1.8V to 5.5V
GBW (MHz)	5.5	5
Slew Rate (V/µs)	1.9	15
V_os max @ 25^oC (mV)	3.5	1.6
Vos Drift, typ (µV/^oC)	---	0.5
Rail-to-Rail	In to V-, Out	In, Out
I_Q typ (mA)	0.3	0.33
V_N (nV/√Hz)	16	20
I_SC typ (mA)	56	50
IBias (Max) (pA)	120000	---

Hi Jerry

Thank you very much for the detailed comparison,

The Slew Rate of TLV9051 is too slow

Could you please suggest products with similar specifications to lmv821 and pin to pin

The slew rate of the TLV9051 is much faster, not slower.

Hey Gareth,

The slew rate of TLV9051 is faster than LMV821. Could you help me help you by providing some more information on the application so I can find you a good alternate part?

Helpful specs would be (but are not limited to)

Channel Count
Vs Range
GBW (MHz)
Slew Rate (V/µs)
Vos max @ 25oC (mV)
Vos Drift, typ (µV/oC)
Rail-to-Rail
IQ typ (mA)
VN (nV/√Hz)
ISC typ (mA)
IBias (Max) (pA)
Operating Temperature (°C)

Without knowing about the application, the best I can provide you is a list of parts we have in DCK package.
